How adaptive practice works
1. You take a short session. Each session is about 15 minutes — roughly the length of one focused study block between classes.
2. Every answer is scored by topic. Instead of one overall percentage, SkoraPrep tracks accuracy for algebra, geometry, data analysis, reading inference, grammar and punctuation separately.
3. The next session is rebuilt. Roughly half the questions come from your weakest topics, 30% from the middle, and 20% from topics you already handle — enough to keep them sharp without wasting time.
4. Difficulty follows your accuracy. Stay above 85% and questions get harder. Drop below 50% and they ease back. You never see the same question twice.
