Greater LA and San Diego host the second-largest USABO talent pool on the West Coast. The San Gabriel Valley schools — Pasadena, San Marino, La Cañada, Arcadia — together with the Orange County prep cluster (Troy, University HS Irvine, Diamond Bar) and Torrey Pines / Canyon Crest in San Diego, consistently send students to Semifinals. PT-evening live classes work for all three sub-regions.
These are the high-USABO-density schools whose students train with us. We've calibrated the schedule, AP-Bio overlap, and Semifinal prep to fit their academic calendars.
Don't see your school? We coach students from any US high school — these are the schools we have repeat enrolments from.
LA and San Diego families weighing options between Curie Learning, individual tutors, and online platforms come to Cerebrum for AIIMS-trained, biology-only faculty teaching at olympiad depth. The Indian small-batch tradition — weekly written feedback, retrieval-heavy methodology, max 12 students per cohort — is exactly what high-achieving STEM students at Pasadena, San Marino, Troy, and Torrey Pines need to convert AP-5 trajectory into Semifinalist standing.
Faculty trained at the All India Institute of Medical Sciences — the same depth-first methodology that produces Indian top performers.
Live classes scheduled in your local US time zone. No 4 a.m. wake-ups, no recorded-only fallback.
10 years of USABO Open + Semifinal papers with our worked solutions and topic tagging. Past-paper drilling is the core method.
Max 12 students per batch. Weekly written feedback on every past-paper attempt. Indian small-batch coaching tradition, not a video library.
Our curriculum maps Campbell Biology end-to-end then layers Alberts and Lehninger. Students preparing for AP-5 finish ahead of schedule.
USABO Semifinalist / Finalist standing is a national-tier credential routinely cited in successful Ivy / MIT / Stanford / JHU STEM applications.
We coach all four stages — and we coach them with continuity. The same faculty who run Open prep run Semifinal and Finals camp prep.
