A significant part of your strategy should include applying scientific inquiry and reasoning skills in the context of natural sciences, with a particular focus on understanding research methods and statistics.

3. Psychological, Social, and Biological Foundations of Behavior

For this section, you will work on reviewing and comprehending psychology and sociology concepts, especially those taught in first-semester college courses. Understanding the interplay between biological, psychological, and social factors is crucial, as is applying scientific inquiry and reasoning skills to social and behavioral sciences. This preparation will be pivotal in grasping the behavioral and sociocultural determinants of health and healthcare.

4. Critical Analysis and Reasoning Skills

To excel in this section, practice analyzing complex texts from various humanities and social sciences disciplines. It would be best to focus on understanding the content and the relationships between ideas or theories in the passages. You need to develop strategies to effectively comprehend and assess the authors' intentions, viewpoints, and tones. These skills include focusing on foundational comprehension and reasoning within and beyond the text.

The MCAT is known for its considerable length, as it is one of the more time-consuming standardized tests for graduate school admissions. The total test length, including administrative and break times, is approximately 7.5 hours. Let’s look at the details:

Test length breakdown:

Examination Time: The four main sections of the MCAT are timed separately. The first three sections – Biological and Biochemical Foundations of Living Systems, Chemical and Physical Foundations of Biological Systems, and Psychological, Social, and Biological Foundations of Behavior – are allotted 95 minutes. The fourth section, Critical Analysis, and Reasoning Skills is slightly shorter, with a time limit of 90 minutes.

Breaks: The MCAT includes several breaks essential for maintaining focus and stamina throughout the exam. There are two 10-minute breaks offered after the first and third sections and a more extended, 30-minute mid-exam break, typically after the second section. These breaks are optional, but most test-takers rest, eat, and regroup during this time.

Administrative Time: Administrative tasks such as check-in procedures, tutorial time, and a post-exam survey also contribute to the overall length of the MCAT test day. While not part of the actual exam, these activities are necessary for testing.
