How important is the MCAT?

The MCAT won't be the only thing med schools look at when evaluating your application, but it is an important component that holds fairly significant weight in the evaluation process, since MCAT scores are generally viewed as correlating well with a student’s ability to successfully complete medical school. Here's how it can impact your medical school aspirations.

A key admissions factor

The MCAT provides med school admissions committees with an objective measure of your readiness and aptitude for medical school. It helps them assess not only your scientific knowledge but also your critical thinking skills, problem-solving abilities, and your potential for success in rigorous med school programs.

Standardized comparison

The MCAT provides a standardized metric for comparing applicants from different educational backgrounds. It helps level the playing field and allows admissions committees to evaluate candidates on a more equal basis.

Competitive edge

A strong MCAT score demonstrates your dedication to academic excellence and ability to perform well under pressure. As such, it can help your application stand out and increase your chances of receiving interview invitations from top-tier medical schools.

Scholarship opportunities

Some medical schools offer scholarships or financial aid packages based, in part, on MCAT scores. Achieving a competitive score can open doors to potential scholarships or other financial support, relieving the burden of medical school tuition.

What is on the MCAT?

The MCAT has four major sections: Critical Analysis and Reasoning skills; Chemical and Physical Foundations of Biological Systems; Biological and Biochemical Foundations of Living Systems; and Psychological, Social, and Biological Foundations of Behavior. While it's essential to have a solid background in subjects like biology, general chemistry, organic chemistry, inorganic chemistry, and physics, the MCAT doesn't test specific medical knowledge.

Instead, the MCAT focuses on assessing your critical thinking, problem-solving abilities, and application of scientific concepts. It challenges you to think analytically, evaluate information, and draw connections between different areas of knowledge.

Do all medical schools require the MCAT?

The MCAT is a widely recognized and commonly required component of the medical school application process in the United States and Canada. However, some medical schools offer early admission programs to undergraduate students, allowing them to secure a spot in medical school without needing to take the MCAT. (If you’re still in high school and are applying to BS/MD programs, check out that guide.)

These programs are typically highly competitive and have specific criteria, such as a strong academic record, completion of specific prerequisites, and involvement in healthcare-related activities.

Examples of med school programs that don't require the MCAT exam

When should I take the MCAT?

It’s generally recommended that you take the MCAT for the final time between January and April or early May during the year you’re applying to med school—as in, if you’re hoping to enroll in a medical school in the summer/fall of 2026, take the MCAT Jan through April of 2025. If you’re still in undergrad and hoping to attend med school the summer/fall following graduation, you’ll want to take the MCAT by May of your junior year.

You can register to take the MCAT throughout the year, starting in January and then from March through September. In 2023, there are 30 MCAT test dates to choose from.

How do you choose the best time to take the exam? Here are some considerations to keep in mind.

Academic preparation

It's essential to ensure you have completed the necessary coursework and have a solid foundation in biology, chemistry, physics, and psychology before taking the exam. Again, college students hoping to start med school immediately after graduating tend to take the MCAT during their junior year.

However, some college graduates take a gap year or more to gain additional experience, conduct research, or participate in medical-related activities before applying to medical school. If you fall into this category, consider how much time you might need to review and refresh the required knowledge for the MCAT.

Study time

Before deciding on a test date, taking practice exams is highly recommended. Practice tests can give you a sense of your current level of readiness and help identify areas that may need more improvement. Taking practice exams under timed conditions can also simulate the actual testing environment, allowing you to gauge how you'll perform on test day.

Based on your practice exam scores, you can determine if you need more time for test prep or if you're on track to take the MCAT within your desired timeframe. Many test takers allocate 2-4 months of dedicated preparation. However, this timeline can vary depending on your familiarity with the content and study habits.

Application timeline

Consider the application timeline and deadlines of the medical schools you plan to apply to. Taking the MCAT early can allow you to receive and review your scores in time to submit your applications during the early or regular admissions cycles.

Most medical schools have application deadlines in the fall or early winter, with interviews typically conducted between September and March. Taking the MCAT early in the year, such as in the spring, can give you ample time to receive your scores, evaluate your performance, and make any necessary adjustments to your application strategy.

Retake possibilities

While aiming for your best performance on the initial attempt is ideal, it's essential to consider the possibility of retaking the MCAT. Some test takers may take the exam early as a practice run to familiarize themselves with the format and content.

However, according to the AAMC's retake policies, you cannot take the MCAT more than three times in one calendar year and four times across two calendar years. You can only take the exam up to seven times in your lifetime.

It's also important to note that med schools will receive all your MCAT scores. So, it's crucial to be strategic and thoughtful when deciding whether to retake the MCAT.

Personal readiness

Aside from academic preparedness, assessing your personal readiness for the MCAT is crucial. Are you emotionally and mentally prepared to tackle the challenges of the exam?

Taking the MCAT requires focus, determination, and perseverance. Be honest with yourself about whether you feel ready to commit to the preparation and the exam itself.
