Exam overview and details

The Medical College Admission Test (MCAT) is a standardized, computer-based examination required for admission to most medical schools in the United States and Canada. Developed and administered by the Association of American Medical Colleges (AAMC), the MCAT is a rigorous assessment designed to evaluate the foundational knowledge and critical reasoning skills essential for success in medical education and practice. The exam comprehensively tests candidates across four sections: Biological and Biochemical Foundations of Living Systems (BBFL), Chemical and Physical Foundations of Biological Systems (CPBS), Psychological, Social, and Biological Foundations of Behavior (PSBF), and Critical Analysis and Reasoning Skills (CARS). A strong MCAT score is a critical component of a competitive medical school application, serving as a standardized metric for admissions committees to assess an applicant's scientific acumen, analytical abilities, and readiness for the demanding medical curriculum. Performance on the MCAT correlates with success in medical school and on subsequent licensing exams, making it a pivotal milestone in the physician training pathway.

Chemical and Physical Foundations of Biological Systems (CPBS): general chemistry, physics, biochemistry, organic chemistry

A 10 kg dancer raises her leg in the air in a développé. Her 2 kg leg is 1 m long and can be assumed to have uniform mass throughout its length. What angle, θ, between the working leg and the standing leg will create the most torque in the dancer’s hip?

Biological and Biochemical Foundations of Living Systems (BBFL): biology, biochemistry, organic chemistry, general chemistry

An antibiotic that inhibits the 30S ribosomal subunit of bacteria would most directly interfere with:

Biological and Biochemical Foundations of Living Systems (BBFL): biology, biochemistry, organic chemistry, general chemistry

A muscle cell that has been exercising vigorously under anaerobic conditions will accumulate which metabolic byproduct?

Biological and Biochemical Foundations of Living Systems (BBFL): biology, biochemistry, organic chemistry, general chemistry

Both maltose and cellobiose share certain features in common. Which of the following is NOT consistent with both molecules?

Chemical and Physical Foundations of Biological Systems (CPBS): general chemistry, physics, biochemistry, organic chemistry

Which of the following compounds is the strongest acid in aqueous solution?

Exam insights and study advice

A competitive MCAT score is non-negotiable for entry into accredited allopathic (MD) and osteopathic (DO) medical programs. It is the primary standardized differentiator in the admissions process, allowing committees to objectively compare applicants from diverse academic backgrounds. High performance demonstrates mastery of pre-medical sciences, advanced critical thinking, and the ability to synthesize information under pressure-all core competencies for a future physician. Beyond admissions, excelling on the MCAT establishes a robust foundation for the United States Medical Licensing Examination (USMLE) Step series and directly impacts opportunities for merit-based scholarships and placement into prestigious medical schools, setting the trajectory for one's entire medical career.

What this exam covers

Use the published domain weights to plan your study. Practice results do not predict your certification exam score.

01Biological and Biochemical Foundations of Living Systems (BBFL): biology, biochemistry, organic chemistry, general chemistry

25%

This section examines biological and biochemical processes in living systems. It integrates concepts from biology, biochemistry, organic chemistry, and general chemistry to explain life at the molecular and cellular levels for medical students.

02Chemical and Physical Foundations of Biological Systems (CPBS): general chemistry, physics, biochemistry, organic chemistry

25%

This section covers the chemical and physical principles that govern biological systems. It requires knowledge of general chemistry, physics, biochemistry, and organic chemistry to solve problems related to biological functions and systems.

03Critical Analysis and Reasoning Skills (CARS): reading comprehension, inference, argument evaluation

25%

This domain tests your ability to comprehend, analyze, and evaluate complex passages. It focuses on reading comprehension, logical inference, and the evaluation of arguments presented in written text to determine your analytical capabilities.

04Psychological, Social, and Biological Foundations of Behavior (PSBF): psychology, sociology, biology

25%

This domain addresses the psychological, social, and biological foundations of behavior. It covers concepts from psychology and sociology as they relate to human biology and behavior to assess your understanding of complex social systems.

Question TypesMultiple Choice (4 answer options), Passage-Based Questions, Discrete (stand-alone) Questions
Retake Policy Up to 3 MCAT attempts per testing year (Jan 1–Dec 31). Up to 4 attempts in any 2 consecutive testing years. Maximum 7 lifetime attempts. All non-voided scores are reported to schools (no score selection). Score release is approximately 30-35 days after the test date. Scores from voided exams or no-shows are not reported.
Exam Format Computer-based, fixed-form (not adaptive); at Prometric test centers only — no at-home option. Four sections with optional scheduled breaks between each section. Total seated time approximately 7 hours 30 minutes (includes tutorial, void option, breaks). Section order is fixed: CPBS, CARS, BBFL, PSBF. Void option: candidate may void all scores at the end of the exam at no cost; voided scores are not reported.
Exam rules No personal items permitted in the testing room. Scratch paper (laminated noteboard and marker) provided at the test center — no outside materials. No unauthorized electronic devices, notes, food, or drinks in the testing room (small snack/drink for break consumption only, stored in locker). Bathroom breaks permitted between sections only (breaks are scheduled). Candidates may opt to void all scores at the end of the exam; once voided, scores cannot be recovered. Attempting to access testing materials or communicate with others during the exam may result in score cancellation and a ban from future MCAT administrations.
