What makes this school special

  • Built entirely around mathematics: every student spends two hours on math each afternoon, with a curriculum running from the standard calculus sequence through college-level algebra, analysis, topology, and number theory
  • Need-blind admissions; for highest-need families the Equal Opportunity Fund covers up to 99% of tuition plus daily transit, lunch, a laptop, overnight-trip fees, and SAT/AP/college-application fees
  • Students map their own multi-year path through a college-level liberal-arts core, with no AP courses and no class rank
  • Draws math-loving students from across the Bay Area, many commuting one to three hours round trip
