Understanding the MCAT and Your Score
The Medical College Admission Test (MCAT) is a standardized, multiple-choice examination required for admission to most medical schools in the United States and Canada. It assesses problem-solving, critical thinking, and knowledge of natural, behavioral, and social science concepts and principles prerequisite to the study of medicine.
The Four Sections of the MCAT
The MCAT is divided into four distinct sections, each designed to evaluate different skill sets and knowledge areas:
Chemical and Physical Foundations of Biological Systems (CPBS): This section tests your understanding of general chemistry, organic chemistry, physics, and biochemistry as they relate to biological systems. It comprises 59 questions.
Critical Analysis and Reasoning Skills (CARS): Often considered one of the most challenging sections, CARS assesses your ability to comprehend, analyze, and reason about information presented in various humanities and social sciences passages. It contains 53 questions.
Biological and Biochemical Foundations of Living Systems (BBLS): This section focuses on biology and biochemistry, examining your knowledge of biological processes, structures, and functions at the molecular, cellular, and organismal levels. It has 59 questions.
Psychological, Social, and Biological Foundations of Behavior (PSBB): This section evaluates your understanding of concepts from psychology, sociology, and biology that underlie human behavior, social interactions, and cultural influences on health. It also consists of 59 questions.
MCAT Scoring Explained
Each of the four sections is scored individually on a scale ranging from 118 to 132. The lowest possible score for a section is 118, and the highest is 132. These are "scaled scores," which means they are not simply the number of correct answers (raw score) but are adjusted to account for slight differences in difficulty between different test forms. This ensures that a score of, for example, 125 on one test date is comparable to a 125 on another test date.
Your total MCAT score is the sum of your four section scores. This means the total score ranges from a minimum of 472 (118 x 4) to a maximum of 528 (132 x 4). A score of 500 is generally considered the average, with competitive scores for top medical schools often falling in the 510+ range.
How This Calculator Works
Our MCAT Score Estimator allows you to input the number of correct answers (raw score) you believe you achieved in each of the four sections. The calculator then uses a simplified, hypothetical conversion model to estimate your scaled score for each section and your overall total score. It's important to understand that the actual raw-to-scaled score conversion used by the AAMC (Association of American Medical Colleges) is proprietary, complex, and can vary slightly with each test administration. Therefore, this calculator should be used as a general guide for understanding how raw scores might translate into scaled scores, rather than a precise prediction of your official score.
Example Calculation
Let's consider a hypothetical scenario:
CPBS: 35 correct answers (out of 59)
CARS: 30 correct answers (out of 53)
BBLS: 38 correct answers (out of 59)
PSBB: 40 correct answers (out of 59)
Using our calculator's estimation model, these raw scores might translate to:
CPBS: ~124
CARS: ~123
BBLS: ~125
PSBB: ~126
Leading to an estimated total MCAT score of ~498. This example demonstrates how different raw scores contribute to the overall scaled score, highlighting the importance of performance across all sections.
Use this tool to get a rough idea of where you stand and to identify areas where you might want to focus your study efforts. Good luck with your MCAT preparation!
