Trigonometry trips up a lot of strong students, not because it's truly hard, but because it's usually taught as a pile of formulas to memorize. Our tutors anchor everything to the unit circle and real triangles, so the identities and graphs finally connect and stick.
Serving students across the East Bay, from Berkeley High, Albany High, and Piedmont High to UC Berkeley and community colleges.

Master the unit circle once and the rest of trig gets dramatically easier. We make it intuitive, not something to cram before every test.
Sine waves, transformations, and identities become predictable patterns once you see the logic behind them.
Our trigonometry tutors are experienced math educators, vetted for clarity and patience.
Strong trig is the foundation for pre-calculus and calculus. We make sure yours is solid before you get there.
I've met with multiple tutors at HPT over several semesters for help in trig, calculus, linear algebra, and differential equations. They saved me from failing a few times. I'm pleased with the useful and professional support I received.
We've used High Performance Tutoring for two subjects, Calc and Chem, and have been very happy. The most important thing was for our son to feel confident, and that's exactly what happened. He came home saying, 'Now I get it.' Highly recommend.
Tutoring with Ingo has been so helpful. He's helping me discover fundamentals I never learned, while showing me I know more than I thought. I appreciate how he breaks down each problem and helps me prepare for similar ones.
My tutor, Ingo, was incredibly helpful in guiding me toward a higher Quantitative GRE score. He was patient and thorough, and I learned more than just how to take the test, I learned fundamental math skills I'd let lapse. I'm really grateful for his help!
An outstanding learning experience! My undergraduate statistics course was very difficult and I had trouble mastering the material. Through one-on-one training, I achieved success. Victor took the time to learn my study habits and created a custom program for my learning style.
By far and away, Christian has been the best tutor. On my PDE exam I got a 91.4%. He conveys the concepts in a way I can understand and explain back myself.
We've used High Performance for two years. Victor helped my son with Chemistry, his grade went from a D to a B+, and he ended up liking the class. They've also tutored him in Algebra and for the ACT. They genuinely enjoy working with the kids, and the kids enjoy working with them!
Victor at High Performance Tutoring is 5 star all the way! He has tutored both my high school kids in math and science. He is reliable, a wonderful teacher, and he really cares about his students. We feel very fortunate to have him on our team.
Liz is a fantastic tutor! Jack has improved his marks significantly in Algebra 2. She has a way of teaching him to attack difficult problems and understand the concepts, with patience and a calm approach.
A belated thank you to Liz for a semester of math tutoring. She essentially taught all of Algebra Honors II. My child received an A in the class and scored in the 99th percentile of the PSAT. We could not have done it without your kindness and teaching skills!
Our family reached out after noticing a drop in our daughter's math grade. The sessions were easy to set up and the tutors were efficient and knowledgeable. We saw an immediate result in her confidence and grade. Would highly recommend for math tutoring.
Victor with High Performance has been an excellent experience. My son started with M3 and is now in AP Pre-Calculus. Flexible, responsibly priced, friendly, and very helpful! I highly recommend this company.
I am a math teacher with a BS in Mathematics, MA in Education, and working on a Master's in Mathematics. For over 10 years, I have …
