Although we are not writing passages to go along with questions, these questions are meant to be similar to the AAMC discrete-style questions, which make up a quarter of each science section. Whereas our Quizlet is meant more for learning the content, these quiz questions test your ability to understand what was taught in this lesson. You should not use percentages from our quizzes to predict your MCAT score, though, since only full length exams and AAMC questions should be used for that.
