Navigating the MCAT: A Comprehensive Guide for Aspiring Medical Students

The Medical College Admission Test (MCAT) is a crucial step for anyone aspiring to study medicine in the United States, Canada, Australia, and the Caribbean Islands. This computer-based, standardized exam is designed to evaluate a candidate's problem-solving abilities, critical thinking skills, written analysis aptitude, and knowledge of scientific principles, all deemed essential for success in medical school.

Historical Context and Evolution of the MCAT

The MCAT's origins can be traced back to the 1920s when US medical schools faced soaring dropout rates, jumping from 5% to 50%. This crisis prompted the development of a standardized test to gauge an applicant's readiness for the rigors of medical education. Physician Fred August Moss and his colleagues created the "Scholastic Aptitude Test for Medical Students," featuring true-false and multiple-choice questions across six to eight subtests. These subtests covered areas such as visual memory, memory for content, scientific vocabulary, scientific definitions, understanding of printed material, premedical information, and logical reasoning. The scoring scale varied across different test forms. Although some criticized the early test for focusing on memorization, later scholars disputed this claim.

Over the years, the MCAT underwent several significant transformations, reflecting advancements in test measurement technology and evolving perspectives on medical school readiness.

Early Modifications

The test was modified to include four subtests: verbal ability, quantitative ability, science achievement, and understanding modern society. All questions were presented in a multiple-choice format. Each subtest received an individual score, and a total score was calculated by summing the scores from each subtest, resulting in a range of 200 to 800. The individual scores aimed to help medical school admission committees differentiate the specific abilities of candidates. However, the "understanding modern society" section, intended to reward students with broad liberal arts skills encompassing knowledge of history, government, economics, and sociology, was often deemed less important by admission committees.

Name Changes and Content Expansion

From 1946 to 1948, the test was temporarily renamed the "Professional School Aptitude Test" before officially becoming the "Medical College Admission Test." This change coincided with the merger of the test's developer, the Graduate Record Office (under contract with the AAMC), with the newly formed Educational Testing Service (ETS). From 1962 to 1977, the MCAT largely retained its existing format, although the "understanding modern society" section was renamed "general information" to reflect its broader content. However, handbooks of the time criticized the test for primarily measuring intellectual achievement rather than the personal characteristics expected of physicians.

Broadening the Scope

During a subsequent phase, the MCAT underwent further changes, including the elimination of the "general information" section and the introduction of a broader range of tested knowledge. Topics now included scientific knowledge, science problems, reading skills analysis, and quantitative skills analysis. Individual scores were reported for biology, chemistry, and physics, replacing the composite science score, resulting in six different scores for the entire test. The score scale was adjusted to 1-15, a departure from the previous 200-800 range. Efforts were also made to minimize cultural and social bias.

Passage-Based Questions and New Scoring

In 1991, the test was revised again, retaining four subtests but renaming them as verbal reasoning, biological sciences, physical sciences, and writing sample sections. While questions remained in multiple-choice format, the majority were integrated into passage sets. These passage-based questions were designed to evaluate "text comprehension, data analysis, ability to evaluate an argument, or apply knowledge from the passage to other contexts." A new scoring scale was implemented, with a total composite score ranging from 3 to 45, based on individual scores for verbal reasoning, biological sciences, and physical sciences, each ranging from 1 to 15. In this format, the exam was administered twice a year (April and August), lasting 8-9 hours with a lunch break, and consisted of 214 questions in addition to essays.

The AAMC announced on July 18, 2005, that the paper-and-pencil version of the MCAT would be discontinued after August 2006.

Content and Structure of the Current MCAT

The most recent version of the MCAT was introduced in April 2015. To determine the content of the exam, the MR5 committee surveyed medical school faculty, residents, and medical students, asking them what concepts entering students needed to know to succeed in medical school curricula. Three separate surveys were sent, focusing on concepts in the natural sciences, research methods, and behavioral sciences.

The current MCAT is a computer-based exam that takes approximately 7+1⁄2 hours to complete, including breaks. It is offered 25 or more times per year at Pearson VUE centers. The exam consists of four sections, each with multiple-choice questions:

Chemical and Physical Foundations of Biological Systems: This section tests chemistry and physics in the context of biological systems. It requires an understanding of organic and inorganic chemistry, physics, biology, and biochemistry. Specifically, this section focuses on the physical principles underlying biological processes and chemical interactions that form the basis of a broader understanding of living systems.
Critical Analysis and Reasoning Skills (CARS): This section is similar to verbal reasoning sections, providing passages with questions testing reading comprehension.
Biological and Biochemical Foundations of Living Systems: This section primarily tests biology and biochemistry but also requires an understanding of organic and inorganic chemistry. Students will have to answer questions about the functions of biomolecules, processes unique to living organisms, and the organization of biological systems.
Psychological, Social, and Biological Foundations of Behavior: This section tests psychology and sociology, requiring students to demonstrate their understanding of the behavioral and sociocultural determinants of health. Specific material tested includes behavior and behavior change, perceptions of self and others, cultural and social differences that influence well-being, and social stratification.

Scientific Inquiry and Reasoning Skills

In the current MCAT exam, changes have been made not only in the content of the exam, but also in the way in which content is presented on the exam. MCAT questions require examinees to demonstrate four Scientific Inquiry and Reasoning Skills that have been identified by the MR5 as crucial to success in science and medicine. The first skill is Knowledge of Scientific Concepts and Principles, which requires students to not only recognize and recall scientific information, but also to identify relationships between similar concepts. Scientific Reasoning and Problem Solving tests the student's ability to relate scientific theories and formulas to presented information to explain findings and draw conclusions. Reasoning about the Design and Execution of Research requires examinees to show that they can understand science in the context of experiments.

Scoring

Each of the four sections is scored from 118 to 132, with a median score of 125. The total MCAT score is the sum of the scores from each section, ranging from 472 to 528, with a median score of 500.

MCAT Score Percentiles

The following are the scores, along with their percentiles from test takers from May 1 through April 30. MCAT percentiles are updated every year on May 1.

Test-Taking Policies and Procedures

The AAMC prohibits the use of calculators, timers, or other electronic devices during the MCAT exam. Cellular phones are also strictly prohibited from testing rooms, and individuals found to possess them are noted by name in a security report submitted to the AAMC. The only item that may be brought into the testing room is the candidate's photo ID.

It is no longer a rule that students must receive permission from the AAMC if they wish to take the MCAT more than three times in total.

Scaled MCAT exam results are made available to examinees approximately thirty days after the test via the AAMC's MCAT Testing History (THx) Web application.

Preparation Strategies

Careful and thorough preparation for the MCAT is critical to your admission to medical school. Start preparation for the MCAT early. Consider that as you begin to take your first premed coursework you are starting to prepare. We recommend looking at the test format and some sample questions while you are beginning to take your first premed science courses, so that you can understand how the scientific principles you are learning in your courses will be used on the MCAT. Do not wait until a few months before the exam to begin preparing for the MCAT. Begin serious study about one year to eight months ahead of the time you plan to take the exam.

Practice Exams and Resources

Take a full-length practice exam one year to eight months before taking the actual MCAT. Use this practice exam to assess your strengths and weaknesses and create a concrete plan to prepare for the exam. Use a set of subject review books along with practice test resources. We highly recommend using all the AAMC practice testing materials, including exams and question packs. These practice questions are written by the same people writing questions on the MCAT so they provide clues about what to expect. In addition, the Khan Academy has developed free MCAT prep resources.

Effective Study Techniques

Take and study practice tests. Prepare intensively through repeated, timed MCAT practice exams and thorough review of the test questions and solutions. It’s easy to get bogged down in months of content review, but successful students spend just as much time working with practice exams. After taking a practice test, go over each problem, and try to reconstruct in your mind what you were thinking when you read it the first time. This will help you identify where your reasoning was correct and where it went wrong. Over time this will help you improve your ability to read a problem, decipher what it’s really about, and avoid falling for the wrong answer.

Key Strategies for MCAT Success

To do well on the MCAT you should strive for three things:

Master the content that will be tested.
Become familiar with the format of the exam itself and understand what kind of information the exam seeks to test.
Practice taking exams to increase your comfort and familiarity with the exam format and to ensure that you time your progress through each section effectively.

Registration and Fees

The MCAT is administered by and overseen by the American Association of Medical Colleges (AAMC). The MCAT is offered about 30 times each year between the months of January and September. It is a computer-based exam. You must register for the MCAT well in advance of when you want to take it. Registration for the April-May exams typically opens in February. Registration for the June-September exams opens a month or so later. Each testing center has a limited number of seats for each test administration.

For the administrations, the cost to take the test is $335 if you register well in advance, but partial fee waivers are available if you apply well ahead of time and can demonstrate financial need. There are rescheduling and cancellation fees as well.

The MCAT's Role in Medical School Admissions

Admissions officers use the MCAT exam as a predictor of your success in medical school. The exam is designed to test the skills you'll use when you get there, including basic science, verbal reasoning, and writing ability. In Canada, most medical schools weigh your MCAT exam scores very heavily.
