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.
Meet Our Berkeley Tutors
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.
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!
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.
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.
High Performance Tutoring got me through stats! As a PhD student, stats is a necessary evil. They met with me twice a week to guide me through challenging assignments. With kindness and intelligence, they showed professionalism and grace.
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!
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.
I had an advanced statistics class my last semester of college that I was really struggling in, and it was stressing me out. Once I got a tutor, my husband said I was like a new person. I finally understood the content and did really well, I passed with a B+ when I think I would have flunked otherwise.
I despise math, but High Performance Tutoring helped me get an A in my medical statistics class. I was admitted to the hospital during finals week and my tutor came to my hospital room and tutored me there for our last session. He was great.
My daughter benefited from Victor's tutoring in Compacted Integrated Math III / Pre-Calculus, and we're signing her up again for AP Calculus next year. He is patient, flexible, and very knowledgeable. We recommend High Performance Tutoring.
We've had a great experience. They were easy to schedule and found the right tutors to help my son through high school. We used them for many topics over the last 4 years, and the last session helped him ace his first college math test. The best thing they gave him was the belief that he could do it himself. Thank you!
As an engineering student at the U, I was struggling with difficult concepts, and I'm so glad I found High Performance Tutoring. Very qualified, professional tutors. You walk away with a better understanding of the subject and perform better in your classes. Highly recommend!
