About 10 minutes. It's 12 questions, one to two per SAT skill area, so it stays short while still covering the whole test.
Because the questions adapt to your answers — harder when you're doing well, easier when you're not — a short test can still place you on the 400–1600 scale. It shows an approximate score band and, more usefully, which skills are costing you the most points. Full timed mock exams inside your study plan then refine the estimate over time.
Yes. The questions match the current College Board Digital SAT (2024 onward): two sections, Reading & Writing and Math, each scored 200–800 for a 400–1600 total.
