Comprehensive Guide to Medical School Requirements

The United States and Canada continue to face a growing need for physicians. Even as some schools expand class sizes and create more training opportunities, admission to medical school remains competitive. For prospective students, understanding the requirements to get into medical school early can make it easier to plan your coursework, gain meaningful experience, and build a strong medical school application.

In this guide, we’ll walk through the main medical school requirements students should know before applying. You’ll learn about common degree and prerequisite course expectations, GPA and MCAT considerations, extracurricular and clinical experience, and other factors that can help admissions committees evaluate your readiness for medical school.

Degree Requirements for Medical School

Most medical schools expect applicants to complete a four-year undergraduate degree from an accredited college or university before matriculating. However, the specific degree students earn can vary. While many pre-med students choose majors in biology, chemistry, or another science field, a science degree is not always required to apply to medical school.

Is a Science Degree Required for Medical School?

In general, students who complete a bachelor of arts (BA) degree can have an equal chance of acceptance compared to students who complete a bachelor of science (BS), as long as they meet the school’s academic expectations and complete the required prerequisite coursework. Admissions committees are often more focused on whether students are academically prepared for the rigor of medical school than on the title of their undergraduate major.

Common undergraduate majors for medical school applicants include:

• Biology
• Chemistry
• Biochemistry
• Psychology
• Neuroscience
• Public health
• Humanities or social science fields

Prerequisite Course Requirements for Medical School

Prerequisite courses are one of the most important medical school requirements to plan for early. These classes help students build the foundation they will need for medical school coursework, the MCAT, and future clinical training. While exact requirements vary by school, many medical programs expect applicants to complete a core set of science, math, and writing courses before applying.

Prerequisite courses can vary by institution; however, common requirements for medical school include:

• Biology: One year of general biology with lab
• Chemistry: One year of general chemistry with lab
• Organic chemistry: One year of organic chemistry with lab
• Physics: One year of physics with lab
• English or writing: One year of English, composition, or writing-intensive coursework
• Math: Coursework in calculus, statistics, or another college-level math course
• Biochemistry: Often required or strongly recommended
• Behavioral sciences: Courses such as psychology or sociology, especially for MCAT preparation

Some medical schools also value coursework in the humanities, social sciences, ethics, public health, languages, or literature. These classes can help students strengthen the communication, cultural awareness, and critical thinking skills that are essential in medicine.

Because the requirements to get into medical school are not identical at every institution, students should review each school’s admissions requirements carefully. A course that is recommended at one school may be required at another. Planning ahead can help you avoid missing key prerequisites and give you more flexibility when building your medical school application list.

MCAT Score Requirements for Medical School

The MCAT is an important part of the medical school admissions process because it helps admissions committees evaluate a student’s readiness for the academic rigor of medical school.

What Is the Average MCAT Score?

MCAT scores range from 472 to 528, with 500 near the midpoint of the scale. A score above 520 is highly competitive. According to the AAMC, the mean MCAT score of students who matriculated to U.S. medical schools in 2025 was 512.1.

‍

When reviewing MCAT scores, medical schools may consider:

• A student’s total MCAT score
• Scores in each section of the exam
• Whether the student has taken the MCAT more than once
• How the score compares to the school’s admitted student or matriculant profile
• How the score fits alongside the student’s GPA and prerequisite coursework

Do Medical Schools Have Different MCAT Requirements?

Medical schools have different expectations and policies when it comes to MCAT scores. An MCAT score that is sufficient for one school might not be for another, especially when this metric is considered alongside grades and the rest of a student’s application.

Some schools publish average MCAT scores for accepted or matriculated students, while others use a broader admissions review process. As you build your medical school list, research each program’s MCAT expectations and consider how your score fits within your overall application.

GPA & Grade Requirements for Medical School

There is often a correlation between GPA and MCAT scores, and medical schools typically consider both metrics when evaluating academic readiness. According to 2025 data from the Association of American Medical Colleges (AAMC), the mean GPA for medical school matriculants in the U.S. was 3.81, while the mean MCAT score for U.S. matriculants was 512.1. However, these numbers should be viewed as benchmarks, not automatic cutoffs.

Medical schools may review several GPA measurements, including:

• Overall GPA: Your cumulative academic performance across all undergraduate coursework
• Science GPA: Your grades in biology, chemistry, physics, math, and related science courses
• Prerequisite grades: Your performance in the courses most closely tied to medical school preparation
• Grade trends: Whether your academic performance improved, declined, or remained consistent over time

A strong GPA can help show that you are prepared for medical school. However, GPA is usually considered alongside MCAT performance, clinical experience, letters of recommendation, personal statements, interviews, and other parts of the application.

Does a Lower GPA Disqualify Me From Medical School?

Students with lower grades are not necessarily out of consideration. Admissions committees may look for evidence of growth, such as an upward grade trend, strong performance in upper-level science courses, post-baccalaureate coursework, or a graduate program. Because GPA expectations vary by school, applicants should research each program carefully and consider how their academic record fits within the broader medical school requirements.

Clinical Experience Requirements for Medical School

Clinical experience is one of the most valuable ways to show that you understand what it means to work with patients. While not every school sets a specific number of required hours, many admissions committees look for evidence that applicants have spent time in healthcare settings and understand the realities of patient care.

Common ways to gain clinical experience include:

• Volunteering in a hospital, clinic, or hospice setting
• Working as a medical assistant, EMT, CNA, or scribe
• Supporting patient care in a community health setting
• Participating in public health or outreach programs with patient interaction

Strong clinical experience should help you reflect on why you want to become a doctor and how you respond to the responsibilities of caring for others.

Shadowing Requirements for Medical School

Shadowing a physician gives prospective students a closer look at the daily responsibilities of a doctor. Unlike clinical volunteering or paid healthcare work, shadowing is usually observational. It helps students better understand physician-patient interactions, care team communication, and the realities of different medical specialties.

Students may shadow physicians in settings such as:

• Hospitals
• Outpatient offices
• Community clinics
• Emergency departments
• Surgical or specialty care settings

Medical schools may not require a specific number of shadowing hours, but they often value applicants who can clearly explain what they learned from the experience. Shadowing doctors in more than one specialty or care setting can also help students make more informed decisions about their path to medical school.

Extracurricular Requirements for Medical School

While coursework, grades, and MCAT scores demonstrate that a student is academically prepared for the rigors of medical school, extracurriculars can tell admissions committees a great deal about how well-rounded and capable an applicant may be. Remember that medical schools are looking for applicants who are most likely to succeed both inside and outside the classroom.

What Extracurricular Activities Do Medical Schools Look For?

A medical school is not going to focus simply on whether an applicant obtained a set number of hours in a particular extracurricular activity. Rather, admissions committees are searching for applicants who are passionate about science, committed to medicine, and interested in providing healthcare to diverse populations. They also want to see leadership skills, service experience, and strong interpersonal and communication skills.

Many medical schools value some combination of the following extracurricular activities:

• Community service: Sometimes called non-clinical volunteering, community service allows students to make a meaningful impact in an area or with a population they care about.
• Research experience: Gaining research experience can demonstrate to medical school admissions committees that an applicant is curious, disciplined, and interested in academic medicine. Being published based on that experience can improve an applicant’s chances, but publication is not required for most applicants.
• Leadership experience: Leadership roles in student organizations, service groups, research teams, work settings, or community initiatives can show maturity, responsibility, and the ability to collaborate with others.
• Teaching or mentoring: Tutoring, peer mentoring, coaching, or serving as a teaching assistant can help demonstrate communication skills and a commitment to helping others learn.

Alongside clinical experience and shadowing, these activities can help admissions committees better understand an applicant’s service mindset, leadership potential, communication skills, and commitment to medicine.

Letters of Recommendation Requirements for Medical School

Letters of recommendation help medical schools understand how others view your academic ability, character, work ethic, and readiness for medical training. While requirements vary by school, applicants are often asked to submit letters from faculty members, advisors, physicians, research mentors, or supervisors who can speak directly to their strengths.

Many applicants seek letters from:

• Science faculty members
• Non-science faculty members
• Physicians they have shadowed or worked with
• Research mentors
• Volunteer or work supervisors
• Pre-health advisors or committee letter writers

Strong letters should offer specific examples, not just general praise. A recommender who knows you well and can describe your growth, professionalism, compassion, or academic preparation is often more helpful than someone with an impressive title who cannot speak in detail about your qualifications.

Personal Statement and Essay Requirements for Medical School

The personal statement gives applicants an opportunity to explain why they want to become a physician. While GPA, MCAT scores, and prerequisite coursework show academic preparation, the personal statement helps admissions committees better understand your motivation, maturity, and sense of purpose.

What Should a Medical School Personal Statement Show?

A strong personal statement should connect your experiences to your interest in medicine. This may include meaningful clinical exposure, service work, research, personal challenges, or moments that shaped how you view patient care.

Many schools also require secondary essays after the primary application. These essays are usually school-specific and may ask about topics such as diversity, leadership, challenges, community service, or why you are interested in that particular program. Together, these written materials help schools evaluate how clearly you communicate and how thoughtfully you have prepared for medical school.

Interview Requirements for Medical School

At many medical schools, the interview is one of the final steps in the admissions process. After reviewing an applicant’s coursework, GPA, MCAT score, extracurriculars, and application materials, schools may invite selected candidates to interview.

Medical school interviews are designed to evaluate qualities that may not be fully captured on paper, including:

• Communication skills
• Motivation for studying medicine
• Professionalism
• Empathy
• Ethical reasoning
• Maturity
• Fit with the school’s mission and learning environment

Interview formats vary. Some schools use traditional one-on-one or panel interviews, while others use multiple mini interviews, often called MMIs. Regardless of the format, applicants should be prepared to discuss their experiences, explain why they want to become a doctor, and show that they understand the responsibilities of entering the medical profession.

U.S. & Canadian Medical School Requirements Versus International Medical School Requirements

Admission to medical schools in the United States and Canada continues to be extremely competitive. Thousands of students apply to these schools each year, and many qualified applicants do not gain admission in a given application cycle. Because of this competition, it is important for students to understand not only the general requirements to get into medical school, but also how those requirements may differ depending on where they apply.

U.S. and Canadian Medical School Requirements

Medical schools in the United States and Canada often place strong emphasis on academic metrics, including GPA, science GPA, MCAT scores, and prerequisite coursework. Applicants are also expected to show meaningful clinical experience, shadowing, service, leadership, and strong communication skills through their application materials and interviews.

Common requirements may include:

• A completed undergraduate degree or required college credits
• Specific prerequisite science courses with labs
• Highly competitive GPA and MCAT scores
• Compelling letters of recommendation
• Clinical, volunteer, research, or leadership experience
• Personal statements, secondary essays, and interviews

International Medical School Requirements

This growing competition, along with increasing admissions expectations, can make international medical schools an attractive and attainable option for some students. Students who apply to international medical schools may find that their MCAT scores and GPAs are considered as part of a larger and more comprehensive picture of their ability.

Applicants still need to show they are academically prepared, committed to medicine, and capable of succeeding in a rigorous medical program. However, some international medical schools may use a more holistic admissions process that considers an applicant’s full background, including academic progress, life experience, clinical exposure, personal qualities, and long-term goals.

For students who are serious about becoming physicians, comparing U.S., Canadian, and international medical school requirements can help them identify programs that align with their preparation, goals, and path forward.
