Thinking about becoming a doctor? Wondering what prerequisites for medical school you need to take? This guide will walk you through everything you need to know. 

Applying to medical school can be exciting and challenging. You’ll want to ensure you’ve ticked the right boxes during your preparation before applying to schools. Every medical school has a unique set of requirements, and it’s crucial to meet them before submitting your application. 

There are often required classes for medical school you must take to apply. But what are these prerequisites, and which do you need to fulfill? We’ll cover a general list of medical school prerequisites, an ideal timeline to follow, and prerequisites for top medical schools. Let’s get started!

What Are Prerequisites? 

Prerequisite courses are classes you must complete before you can attend a program. These courses are essential tools for success. Professors will refer to what you’ve learned from these courses throughout your program, so completing them is critical.

Other than helping you gain valuable knowledge, certain prerequisites are mandatory. A program may reject you unless you’ve completed its prerequisite courses. Check the application requirements for your program long before you intend to apply to give yourself time to prepare.

Examples of med school prereqs are biology, chemistry, physics, mathematics, and English. These courses help you build the foundational knowledge you need to succeed in medical school.

Common Med School Prerequisites

Now you’re probably wondering what prerequisites you need for med school. All medical schools require proficiency in science and math. Beyond these courses, some schools have expanded their required courses to include English, psychology, sociology, and biochemistry.

Common Required Courses

Let’s review each standard prerequisite course for medical school.

Other Prerequisites

Now, let’s cover other prerequisites for medical school.

Ideal Timeline for Medical School Prerequisite Courses

Before applying to medical school, you should give yourself at least two years to decide which schools you plan to apply to. Every school has different requirements, so you should give yourself ample time to take prerequisites before applying. 

You should also include other differentiating activities to add to your application in this timeline. You should allot time to get clinical experience, research experience, volunteer, acquire recommendations, take your tests (multiple times if necessary), and take prerequisite courses. 

You can take up to five courses a semester at any typical university. It would probably be best to spread out these courses as they’re intense, and you’ll need time to prepare for other areas of your application.

Medical School Prerequisite FAQs

Here are answers to the frequently asked questions about prerequisite courses for medical school. 

1. What Are the Prerequisites for Medical School?

Every medical school has different prerequisite requirements. Generally speaking, most schools require biology, chemistry, physics, mathematics, and English.

2. Are There Medical Schools Without Prerequisites?

Many medical schools do not have prerequisite course requirements, so you can apply to med school without them. However, prereqs will prepare you for your future courses. You can take a pre-med program to build the foundational knowledge you’ll need. 

Some medical schools without prerequisites include:

All of these programs require a bachelor’s degree. Although they do not have specific prerequisite courses, they still highly recommend a strong background in science. 

3. Can You Retake Med School Prerequisite Courses?

If you’ve done poorly on a prerequisite, you can always retake it. Before doing so, you should research your school’s stance on retaking prereqs. Depending on the school, retaking courses can potentially damage your applicant profile.

4. How Many Prerequisites Do I Need for Medical School?

Generally speaking, you should plan to complete at least one year of biology, chemistry, and physics, all with labs. It would be best if you also planned for a minimum of one year of English and math.

5. Can You Take the MCAT Without Taking Prerequisites?

There are no required courses for the MCAT. However, taking the MCAT without prerequisites is not recommended. Prerequisite courses provide opportunities to take notes, ask questions, and study with peers. If you plan on taking the MCAT without prereqs, seek guidance from a tutor.

6. What Courses Should I Take Before the MCAT?

It’s good to take all the prerequisites for the program you’re considering. You should build your knowledge by taking biology, chemistry, physics, mathematics, and English courses. 

7. Do Medical School Prerequisites Expire?

Most medical schools do not have a specific expiry date for prerequisites. If you wonder if your prerequisites will be acceptable, speak with an academic advisor or admissions consultant. 

8. How Long do Prerequisites Take to Complete? 

Most medical school prerequisites require one year of study, though some require two or more. It’s a good idea to spread them throughout your undergraduate study to ensure you’re fully prepared for medical school. 

Final Thoughts 

Many medical schools do not require prerequisites, but they are always recommended. Prerequisite courses are valuable tools to help build your knowledge before medical school. They’ll make your tests less stressful and your journey through medical school more manageable. 

Some schools have a long list of mandatory prerequisites, so you should research the prerequisites of each school you are interested in at least two years before you begin applying. Remember, while you could cram every prerequisite into one year, it will be stressful, and you may want to give yourself more time.

Generally speaking, every medical school will want you to grasp biology, chemistry, physics, math, and English before entering your degree. To be safe, you may also want to add biochemistry, anatomy, psychology, and statistics to your course load.
