This section comprises 59 questions with 10 sets of 4 to 6 passage-based questions and 10 independent questions to be answered within 95 minutes.

In this section 65% of the questions are dedicated to Biology, with a quarter (25%) to biochemistry, 5% to general chemistry, and the other 5% to organic chemistry. Test-takers are challenged to demonstrate their knowledge of molecular biology, cellular processes, and the principles of living systems, equivalent to those taught in undergraduate courses. 

Section 2: chemical and physical foundations of biological systems

The Chemical and Physical Foundations of Biological Systems segment evaluates a candidate’s grasp of foundational concepts in chemistry and physics as they apply to biological systems. In this section, MCAT test takers are challenged to showcase their theoretical knowledge of physical and chemical knowledge in combination with reasoning skills. 

With equal questions as other sections—59 questions in total— test-takers have 95 minutes to showcase their knowledge. Close to two-thirds (30%) of this section is allocated to General Chemistry, while biochemistry (25%) and physics (25%).  The other 15% of the questions go to organic chemistry and 5% to biology.

Section 3: psychological, social, and biological foundations of behavior

Section 3 focuses on the interplay between psychology, sociology, and biology in shaping behavior and societal dynamics. Test-takers are tasked with applying their understanding of how biological, psychological, and sociocultural factors influence behavior and social interactions. Questions of this section are equivalent to the materials taught in undergraduate courses, specifically first-semester sociology and psychology classes. 

This section comprises 59 multiple-choice questions and allows 95 minutes for completion. Over two-thirds (65%) of these questions are about psychology, with the other 30% about sociology and 5% about biology.

Section 4: critical analysis and reasoning skills

The final section, Critical Analysis, and Reasoning Skills assesses a candidate’s ability to comprehend, analyze, and evaluate information from various sources. Unlike the other sections, it does not focus on specific content areas but on applying critical thinking skills. Test-takers are presented with passages (about 500 to 600 words each) and questions that require them to draw logical conclusions, analyze information, and critically assess arguments. This section evaluates the aptitude for critical thinking and effective communication.
