Why practice with questions?
Reading and highlighting make you feel like you understand a topic, but an exam doesn't ask you to recognize text you've already seen: it asks you to recall and tell similar options apart. Answering questions forces you to pull information out of memory, and that effort is exactly what makes it stick. It also shows you clearly which topics you haven't mastered yet.
These guides explain how to use that principle with your own material, and how to use the Exam Simulator to practice with lives-based timed exams, practice mode and mistake review.
