Liberty High in Brentwood offers a compacted Algebra 2/Precalculus class that covers both courses in one year on the way to AP Calculus. Our tutors are UC Berkeley students who took many of the same courses not long ago, from forensic science to AP Calculus BC.
Tell us about your student, and we’ll match them with a UC Berkeley tutor who fits.
We help Liberty students keep up in their classes, prepare for the SAT and ACT and work on their college essays. Sessions are one-on-one, at your home in Brentwood, Oakley or Discovery Bay, or online.
Meet our tutors
Two math courses in one year
In the compacted course, trigonometry arrives while students are still getting comfortable with Algebra 2. Word problems are where the two meet, like a Ferris wheel whose height rises and falls with time. With a tutor, your student sketches the height over one full turn before writing any equation. Learn more about our math tutoring.
Case reports in Forensic Science
Liberty’s Forensic Science students write case-study reports on real and simulated crimes. The hardest part of a report is matching the strength of the claim to the strength of the evidence: a partial fingerprint suggests, it doesn’t prove. A tutor reads your student’s draft and asks, for each conclusion, how sure the evidence really lets them be. Learn more about our science tutoring.

A separate year for BC
At Liberty, AP Calculus BC follows AB as its own year, giving students time to extend the calculus they already know. That year is where series show up, and they feel unlike anything before: an infinite sum that adds up to a finite number. A tutor starts with sums your student can picture, like halving a distance again and again. Learn more about our math tutoring.
