Physics Tutors Who Reveal the DNA of the Universe
Physics is simple rules commanding complex phenomena — conservation of energy explains nearly everything you will ever see. Your student’s physics class probably never said that. Ours does, and then hands them a method so they always know how to start.

Meet computational physicist and resident closer Jonathan Lupercio.
Research physicist turned tutor. Seven of his physics students so far have gone from an F to a B+ in half a semester — which is why, internally, we call him the Closer.
Jonathan Lupercio
Jonathan earned his B.S. in Physics with a mathematics minor at Stony Brook University, where he worked as an undergraduate researcher in the Fernandez-Serra group on computational physics — simulating how physical systems behave, rather than reading about them.
He is the tutor we send when a semester is already going badly. Seven times now, a student has come to him failing physics and finished half a semester later with a B+. He teaches math, physics and chemistry at every level, along with SAT, ACT and Regents preparation, and he is the person for the student who can do the algebra but cannot picture what the system is doing — which is most students in physics, most of the time.

- Undergraduate researcher, Fernandez-Serra group (computational physics)
- Physics department tutor, Stony Brook University
- Teaches math, physics, chemistry and test prep at all levels

The Alexander Difference
Passion + Purpose = Empowered
When math serves your student’s passion, it has purpose. When it has purpose, something remarkable happens — they become empowered to use education to achieve their dreams.
Personalized Matching = Student Passion
We start by learning what lights your student up — music, sports, art, science, anything. Then we match them with a tutor who shares that passion and shows them how math is the hidden engine behind the things they already love. When math serves something they care about, it stops being a chore.
“His high school teachers were great, but were not able to provide the depth and level of support that was needed… His grade went from a C- to an A- within the year. He is now averaging an A in a dual enrollment college algebra course, and planning to take college calculus next year.”
— Krystal M., Parent (Google)
Deep Understanding = Purpose
Most students survive math by memorizing formulas — until one curveball on the test sinks them. We teach the why behind every equation, deriving formulas and connecting them to the real world. When your student truly understands the math, they can solve anything a teacher throws at them.
Confidence First = Empowers Students
There’s no such thing as being ‘bad at math’ — only bad math experiences. A harsh teacher, embarrassment in class, one bad test — and suddenly your student decides they can’t do it. We rewrite that story. With a supportive tutor who believes in them, ‘I can’t’ becomes ‘I’ve got this.’
Everything changed for these families.
Alexander tutoring is the whole 9 yards in terms of providing student-centered tutoring for physics and math. Starting from making the right student to tutor match by considering personality and learning styles and focusing on the foundational concepts that establish cumulative learning. Our experience with Alexander Tutoring has been nothing short of excellent. In addition to understanding both physics and calculus concepts that have resulted in improved grades (an A in physics!), my daughter has gained a new found confidence and joy that comes from learning and comprehension. I can’t say enough about the individuals on the Alexander Tutoring team who make this possible every week! Thank you Rebecca (physics) Gerard (calculus), Sean and Jill!
When my daughter was looking to go beyond her middle school math class, we were fortunate to find Alexander Tutoring. My daughter worked weekly with her fantastic tutor, Jonathan, throughout 7th & 8th grade. He not only helped her fill in the gaps in Algebra I so that she was able to successfully place into Honors Algebra II for high school (her goal!), but was also super flexible and engaged with her in exploring advanced conceptual math (for example, venturing into trigonometry and calculus, and particularly quantum physics) The online platform, which she was apprehensive about at first, worked really well, and she always looked forward to going online for her tutoring sessions. We would absolutely continue with Jonathan in high school, and I wouldn’t hesitate to work with Alexander Tutoring again to provide support for my younger daughter, who struggles with math, as she heads into middle school.
My daughter was feeling wholly defeated and distressed by her Honors Trig & AP Bio classes. To the point she was considering dropping her STEM-focused hopes for college. She started working with Rebecca and that changed everything. Rebecca identified challenges, shored up her foundational skills, and taught her methods and practices that she could build on. My daughter’s confidence and competency made a dramatic about-face, and her outcomes on both tests and transcript reflect that shift. She feels confident about the upcoming challenge of Physics and Statistics next year, knowing Rebecca, and her colleagues at Alexander Tutoring, are available to support her.
Alexander Physics and Math Tutoring has been a fantastic partner to us for two of our kids in high school physics and middle school math. Both kids agree the extra help and attention on their school material made a big difference, because the tutors who took the time to get to know them and how they best learn. We saw the results in their test results and, more importantly, in their positive attitudes toward these subjects that had previously caused them stress. Special kudos for Rebecca and Gerald!
Alexander Tutoring (AT) is a premium, high-end, math and physics tutoring service. We are extremely grateful to Sean Alexander and the AT staff for helping our de-motivated 16 year old son reverse his declining pre-calculus grade during the COVID-19 pandemic. AT was able to help our son improve by a full letter grade in just four weeks, and was worth every penny we invested in the process. The AT staff is very professional, high energy, friendly, and adaptable. We are delighted to be working with them to help our family continue to develop math and physics acumen. A+ service!
Alexander Tutoring (AT) has been a godsend for our son who's been struggling in pre-calculus since COVID-19 kicked in. Our son's grades were on steep decline since the start of the school year. AT came in and was able to get our son up a full letter grade in just four weeks. They've been terrific to deal with; are extremely flexible, and are driven to help spread the languages of math & physics to the world (math is the language of the universe!). AT has gone far above and beyond on working with us to get our dispirited teenager back on track during this challenging pandemic. Thank you to Sean Alexander and the staff at Alexander Tutoring!
Alexander Math and Physics tutoring is truly a superior tutoring service. My daughter was really struggling with math and physics at the beginning of her Freshman year and after starting tutoring once a week her marks started improving immediately! By the end of the year, she achieved an A+ in physics and an A in math! Sean was not only excellent in working with my daughter, he was very organized, reliable and accommodating if I ever had to change the day, or get extra sessions for finals etc.. My daughter has more confidence going into Sophomore year and we couldn't be happier with this excellent tutoring service. This was an amazing success story and I very highly recommend this tutoring service to everyone!
We discovered Alexander Tutoring via a web search and decided to give it a try because of the rave reviews. We were not disappointed! Jonathan has been teaching our 2 kids Math and Physics and his teaching approach, patience and attentiveness has greatly improved their interest in and aptitude for the courses! Jonathan is always punctual. His patience with the children encourages them to ask questions and he diligently takes the time to explain. My wife and I were a bit concerned about the schedule of the classes, because of the time difference between Africa and the West Coast. However, Sean was flexible and committed to finding a time that worked for both parties. We are really delighted to have found Sean and his team!
Sean Alexander and his team are such kind, intelligent experts in their areas of mathematics and physics. At Gifted Support Center we have referred many families and they all report how much their children love working with their tutor/mentor. On a personal note, Albert was amazing in working with my son. I can't say enough praise for Sean and what he has created at Alexander Tutoring. Passionate individuals who truly love their field, and love teaching and inspiring children.
Jonathan is currently tutoring my son in eleventh-grade physics. Josiah has an A in Physics and more importantly, he feels he has a good grasp and confidence in the subject. Jonathan is patient and has a strong comprehension of physics. He's very adaptable and helpful when Josiah has a structured assignment or when they are practicing concepts. He is punctual for all their appointments and communicates before each meeting to make sure both parties are on the same page. Lastly, Jonathan is very respectful and always has a positive attitude.
My son, a chemistry major at Northeastern, has been tutored by Jonathan for about a year. When he met Jonathan, mid-semester, he was close to failing physics 2. He ended the semester with a B+! Now he is working with Jonathan on mastering physics 3. Jonathan helps him work through problems and provides a deep conceptual understanding. He is the key that has helped my son move from surviving to thriving!
Sean and his star teacher Jonathan are amazing. I was stuck in finding the right teacher to support my 7 years old son’s learning needs, who has unusual passion to quantum physics but only have poor primary school math knowledge. It’s almost mission impossible! But Jonathan did it! Can’t be happy more!
My daughter has been working with Jonathan from Alexander tutor. She's being tutored with AP Physics, and Jonathan has been such a great instructor. He has the best way in helping my daughters. He's very patient, very kind, very encouraging and always goes the extra mile to help my daughter. I have seen how she looks forward to tutoring with Jonathan and how her stress level has gone down towards the end of her 1st Junior semester! We are so appreciative for Alexander tutoring services. And so excited that my daughter was paired with such beautiful, compassionate and understanding human being, Mr. Jonathan! Thank you, Alexander Tutoring! Erica (0/21/2020)
Set your kids up for success...the best advice one of my friends gave me was to start my son with Alexander Tutoring before he started his freshman year at an independent high school. My son was a progressive middle school and I was not really sure how he would fare with Physics and Algebra. Alexander tutoring was amazing in that Sean assured me that my timing was just right at the beginning of the school year and we engaged with Felix (my son's tutor) right away. My son and Felix meet on a weekly basis and even though..or more accurately because my son is getting As in both Physics and Math, we are keeping the tutoring going!
Sean and his team are great. I work at a school and have referred many students to him for math and physics, and sometimes for other sciences. He is a wonderful tutor, great with kids, willing to coordinate directly with teachers for maximum efficacy. Highest rating!
Alexander Tutoring is excellent. My daughter attends a very rigorous high school in SF and has worked with Tyler to solve problems in Physics, Chemistry and Algebra 2. He explains tough concepts through relatable and fun examples and she truly looks forward to their weekly sessions. He has also been flexible when other commitments required a time change or when she needed additional help before a test.
My daughter is a senior at high school and is doing honors Physics. She wants to enroll for the AP physics tests as well. During her classes at high school she was struggling with the physics,so we decided to ask Sean for help. Our daughter said that Sean can explain it very well and she was so relieved that she can understood much better the theory. It gave her a big push for her self esteem and that she will not fail in her honors class physics. Highly recommend Sean!
Sean worked with my son during the later half of the year for my son's 12th grade AP Physics C course. The course was very difficult, but Sean was able to explain things in ways that made sense to my son, and my son also enjoyed working with him and really felt he "clicked" as far as understanding him personally. My son further said that Sean was a "cool guy who made the tutoring sessions enjoyable" for what was a really tough class. Based upon my son's experience, I would highly recommend Sean to anyone needing a Physics tutor!
After SF public schools ended their honors math programs I was looking for a way for my 8th grader to qualify for high school honors Math. I am happy to report that Tyler at Alexander Math and Physics tutoring helped my son to test into Algebra 2 honors! His math grade in school went up to an A. Then when we told him he could stop tutoring with Tyler he didn't want to stop tutoring because he enjoyed what he was learning. Wow! My older son is now preparing for the Physics and Math subject tests and Alexander Tutoring is where we are going. I am so thankful to have advanced Math and Physics help for my kids.
Sean offers great tutoring. My son was a Senior in High School, and the AP physics had become very difficult for him. He had become very stressed, and his grades were getting worse at every tests. After starting tutoring with Sean, he started to feel more relax about physics, and had a good grade at his International Baccalaureate. Sean knew how to make him approach the tests in a more relax way. Sean's help was priceless. Thank you, Sean.
This is the Cadillac (or Tesla? Bentley?) of math/science tutors! Tyler helped my child survive AP Physics with a really poor high school teacher. Tyler taught underlying concepts, reinforced necessary Calc lessons, and diagnosed roadblocks before they became problems. He worked with a complicated schedule and was flexible. More importantly - when there were critical tests or problems, Sean and Tyler jumped in and did whatever was necessary to provide emergency Physics triage! As a result: our child learned that hard work, a tough attitude and commitment can get you through ( while several classmates blame the teacher and complain constantly.) And she loves them so much she declined summer vacation so she could spend the month before college starts reviewing Calc and learning to code. They are worth everything.
Throughout my high school career, I haven't had a better tutor than the one I worked with through Alexander Tutoring. Physics has always been a difficult subject for me, but thanks to my tutor, Tyler McGoffin, it became very accessible. Tyler explained abstract concepts in simple terms, grounding them in the real world and enabling me to understand them. Tyler and I bonded very closely during our time together, and I came to see him not only as a tutor but as a friend. Alexander Tutoring provides fantastic services, and I know that anyone else who works with Tyler will be as happy as I am.
My daughter is a senior at highschool and is doing honors Physics.She wants to enroll for the AP physics tests as well.During her classes at highschool she was struggling with the physics,so we decided to ask Sean for help.Our daughter said that Sean can explain it very well and she was so relieved that she can understood much better the theory.It gave her a big push for her self esteem and that she will not fail in her honors class physics.Highly recommend Sean!
My high school son has been working with Olivia at Alexander Math & Physics Tutoring for about 7 months and it has been nothing less than phenomenal! My son's confidence in Math as well as his grades have drastically improved and we could not be happier!! Also, Sean and Olivia have both been incredibly flexible in their attempts to accommodate our busy schedules. We are very grateful to have discovered Alexander Math & Physics Tutoring!
Sean has been a great tutor for my daughter in both physics and math. I was really worried about my daughter tackling pre-calculus this year but Sean could always explain any new material in a way that she could understand and she ended up doing very well. I really liked how after each session Sean would email me and let me know how things were going.
This is the first time I've posted a Yelp review, and I hope it is not to our detriment as the word spreads! I have only good things to say about Alexander Tutoring for physics support. Sean Alexander, the founder (also a tutor), has two incredibly talented physics tutors, Olivia and Tyler. They are the BEST, making tough physics concepts comprehensible. Sean is personable, responsive, and accommodating with scheduling. He is also kind, fair, and generous. When Olivia ran just a few minutes late for the first session, Sean took 10 minutes off the hour; and when I asked if he had a referral program, he gave us a free session for referring a friend whose son is now benefiting from weekly physics sessions. He is open to feedback and sincerely wants to help. A rare breed.
My daughter took an intensive high school Physics course this summer and had to miss a few days of instruction due to a family commitment. She was so worried about falling behind in her course - but with the help of Alexander Tutoring and, specifically, Tyler, she had nothing to worry about. The owner of Alexander Tutoring, Sean, was so helpful in getting my daughter squared away with tutoring sessions even though we called him fairly last minute. And the tutor my daughter was assigned to, Tyler, was wonderful. He and my daughter had three sessions and she was right back on track in her course. She really enjoyed working with him and would highly recommend him to anyone needing help with Physics.
As a senior in high school, my son needed urgent help with his IB French Physics course. He had been struggling on and off with the course since his junior year. With only a month before his IB exams, he did not think he would pass the physics exam. Sean worked with us to find the right tutor for my son. In just 8 sessions, Tyler was able to clarify everything that was giving my son trouble, and he more than just passed his IB exam! Tyler is excellent! We do wish we would have found Sean and Tyler earlier. We highly recommend Tyler and Sean.
Desperate for some help with a challenging 9th grade physics class, we turned to Alexander Tutoring. Sean was very responsive and got my son set up right away with Tyler, tutor extraordinaire. Tyler is down to earth, extremely intelligent and was able to connect with my son on his level and make physics seem less daunting. It was worth the time and investment to turn things around and most importantly, give my son the confidence that he needed to face the challenge. Thank you, Alexander Tutoring! We'll definitely be back to take advantage of other programs they offer (like the SAT Master Class.)
Hands down, Alexander Tutoring is the best in the Bay Area. After trying other highly rated tutors with no success, we were relieved to find Alexander Tutoring. The director, Sean, spoke with me at length to assess my son's needs and pair him with the right tutor. He even met with my son's teacher to better understand his needs. My son was paired with Tyler and from the first meeting his interest and ability in math and physics have steadily improved. My son even took The coding course over the summer and is well on his way to designing his own game. I cannot recommend Alexander Tutoring highly enough.
Why physics students freeze
Students stall in physics because they think they need the whole solution before they write anything down. I do not know the whole solution either. I follow eight steps and trust that they will get me there — and that is exactly what we teach your student to do.
Then we fix what is actually broken, and it is almost always the same things. That gravity is not inherently negative; the coordinate system decides the sign. That acceleration due to gravity and force due to gravity are different things. That vectors add tip to tail, which is the whole meaning of components. We have heard “because gravity” a hundred times, and it is never the student’s fault — it is what happens when a class teaches formulas instead of systems.
And we give back what the curriculum cuts. Relativity. Quantum mechanics. That your relative velocity changes how your clock runs, that observing an experiment can change its outcome, that the atoms in your hand could in principle pass through a wall. Was any of that in your high school physics class? It is in ours.
What Our Physics Tutors Cover
Our tutors are physicists. Not math teachers who also cover physics — people who have done research in it. That difference shows up fastest in physics, where the gap between plugging into a formula and understanding a system is widest.

From Freshman Physics to AP and IB
We tutor every level of high school physics, and a lot of our students start in 9th grade.
- Freshman physics. Many Bay Area high schools put physics in 9th grade, before chemistry and biology. It is usually conceptual or algebra-based, and it arrives while students are still learning algebra. That is the hard part: a student stuck on a motion problem is often stuck on the algebra inside it. We untangle the two, so the physics makes sense and the algebra gets stronger along the way. It is also the year a student decides whether they are a “physics person,” which is why we like to get in early.
- Honors and regular physics. The standard high school course in 10th, 11th or 12th grade: mechanics, energy, waves, electricity and an introduction to modern physics, with more algebra and trigonometry than freshman physics.
- AP Physics 1 and 2. Algebra-based, equivalent to the first and second semesters of college physics. AP Physics 1 covers kinematics, forces, energy, momentum, rotation, oscillations and fluids; AP Physics 2 covers thermodynamics, electricity and magnetism, optics, waves and modern physics (College Board). The 2027 AP Physics 1 exam is on May 5.
- AP Physics C. Mechanics and Electricity and Magnetism, taught with calculus. A student who is shaky in calculus often stalls on the physics, so our tutors can work on both in the same lesson, and our calculus tutors cover AP Calculus AB and BC.
- IB Physics, SL and HL. A two-year course built around data, experiments and an internal assessment worth 20% of the grade. It is a specialty of ours: our IB Physics guide covers SL vs HL, the five themes, the papers, the data booklet and the IA, and our IB math and physics overview covers the Diploma as a whole.
- College physics. Algebra- and calculus-based College Physics I and II.

Physics Tutoring FAQ
My child is taking physics as a freshman. Can you help?
Yes, and it is one of the most common courses we tutor. Freshman physics arrives while students are still learning algebra, so most of the struggle is the algebra inside the physics. We work on both together, which makes the physics click and strengthens the math for the years ahead.
Which AP Physics course should my student take first?
AP Physics 1. It is the algebra-based first-semester course, and the College Board recommends taking it before AP Physics 2. Students who are already in calculus can go straight to AP Physics C.
Is AP Physics 1 hard?
It is one of the more demanding AP courses because most questions ask students to reason about a system and explain it, not just plug numbers into a formula. Students who learn to start from the governing principle, such as conservation of energy or Newton's second law, find it far more manageable.
Do you tutor IB Physics and college physics?
Yes. IB Physics at Standard and Higher Level is a specialty of ours, including the internal assessment. We also tutor College Physics I and II, both algebra-based and calculus-based.
Who are your physics tutors?
Physicists, not math teachers who also cover physics. Every tutor has done research in the field. You can meet the team before you book.
What if tutoring doesn't work?
We guarantee results for the entire semester. If you're not satisfied at the end of the term, we refund every penny. Your first lesson is risk-free, so you can see how it works before you commit.

Most tutoring gets a student through Friday’s test. That’s not what we’re for.
Your student learns where every formula comes from — so a problem they’ve never seen stops being a threat. They stop asking whether something will be on the test and start asking why it works.
