BASIS Independent Silicon Valley teaches biology, chemistry and physics as separate classes in sixth, seventh and eighth grade, and its students can begin AP courses as early as eighth grade. Our tutors are Stanford students who took the same subjects at a high level and know how to keep a student moving at that pace.
Tell us about your student, and we’ll match them with a Stanford tutor who fits.
We tutor BASIS students in everything from pre-algebra and middle school chemistry to AP Calculus BC and AP sciences, and help with AP exams and the senior research paper. Sessions are one-on-one, at your home or online.
Meet our tutors
AP exams that count
Every BASIS student takes at least four AP courses, and the AP exam serves as the course’s final exam, so the score goes into the final grade. Passing at least one AP exam is required to graduate. A tutor helps a student review steadily through the year, work through real past exam questions, and go into the exam ready. Learn more about our test preparation.
Middle school math and science
BASIS students start pre-algebra in sixth grade and take an accelerated algebra and geometry sequence from seventh, earning high school credit in Algebra I, Algebra II and Geometry before ninth grade, when most begin Precalculus. A tutor fills in any gaps quickly, so a student who stumbles on one unit doesn’t fall behind for the rest of the year. Learn more about our math tutoring.
