RollSAT is an independent, student-built study tool for Digital SAT practice and Bocconi application planning. The useful parts stay free: no paywall, paid tier, card requirement, or question limit.
RollSAT uses College Board question-bank material for personal SAT practice and links to College Board for official full-length testing. The Bocconi tool keeps published selection rules separate from self-reported programme benchmarks and never presents an exact acceptance probability.
Practice questions are fetched from the College Board question bank and rendered in a study interface with filters, Desmos, notes, review scheduling, and adaptive modules.
The calculator labels the 55% test and 45% GPA weights as official public criteria. SAT normalization, programme anchors, and qualitative risk bands are marked as unofficial estimates.
If a question renders incorrectly, a source changes, or a benchmark needs stronger evidence, report it directly. Corrections are preferred over defending a bad estimate.
