The MCAT Structure

The MCAT is a multiple-choice, computer-based, standardized test. Each section includes some trial questions that are being considered for possible inclusion in future MCAT exams—and those questions are not included in your final score. Of course, you won’t know which are trial questions and which questions are graded.

MCAT Study Tips

Sections 1-3

For MCAT sections 1-3: As you complete your prerequisite course work for these three sections, practice applying the concepts. Developing the habit of using challenge questions at the end of your textbook chapters can help you build the stamina and agility needed to conquer these sections.

Section 4

For MCAT section 4: Become a voracious reader. Digesting and discussing novels, biographies, news, and academic journals will build your critical analysis and reasoning abilities. Even better, practice these skills by joining a discussion group such as a book club or debate team.
