How our adaptive system works
Targets your weak areas
After each answer, questions are selected from the categories where your accuracy is lowest — so you spend time where it counts.
Avoids recent repeats
The last 20 questions you answered are excluded, so you're never stuck in a loop on the same material.
Detailed explanations
Every answer choice gets its own explanation — not just why the right answer is correct, but why each wrong answer is wrong.
Track by category
Your dashboard shows accuracy per subject so you always know exactly where you stand across all Step 3 topics.
