Where these come from
SAT Climb’s question bank holds 17,599 items across 31 skills and three difficulty tiers. The 775 here are all drawn from the hard tier, which is 4.4% of the bank and roughly the top end of what shows up on a real test. The other 16,824 sit inside the app, alongside the diagnostic that tells you which skills are actually costing you points.
Questions are written by SAT Climb and drawn from its own item bank. SAT® is a registered trademark of College Board, which is not affiliated with and does not endorse SAT Climb.
