Personal SAT study plan + Mistake Bank that spots your weak points.
Every missed question goes into your Mistake Bank. Your Study Plan ranks the topics you're weakest on. Pacing analytics show where you're spending too long, so tomorrow's session is always the right one.
Every wrong answer comes back at the right time, 1 day, then a week, then a month, until you've got it.
Ranks your weakest topics so tomorrow's 30 minutes go to the right place, not just whatever you tap.
Spots the questions where you're 2× slower than your topic average, and tells you exactly what to retry.
