Table of Contents

Quick reality check—less than half of the total applicants get into U.S. medical schools each year. But don’t freak out just yet!

You’ve got control over a huge piece of this puzzle, and that’s your undergrad course load. Picking the right premed courses is huge—it’s what sets you up to crush the MCAT and make med school admissions committees raise an eyebrow (in a good way).

Let’s face it—there’s a mountain of advice out there. You’ve probably heard a hundred different takes on what classes to take. Some people say this, others say that. 

So, what’s the truth? Well, no more guesswork. We’re going to break down exactly what you need to focus on—starting with the absolute must-takes, then moving on to the “if you really want to stand out” courses, and rounding things off with some nice-to-haves if you can squeeze them in.

Must-Take Courses Every Premed Student Needs

If you do nothing else, do these. These classes are non-negotiable. They’re like the foundation for everything you’ll do in med school and beyond. 

And yep, they show up all over the MCAT too. So skipping them? Nope, not an option.

Biology

Biology 1 & 2: The Foundation of Medical Science

Let’s start with an obvious one—Bio 1 and 2. You’re going to be swimming in biology for the rest of your life, so might as well get comfy with it now.

Here’s why it matters:

  • Prerequisite for almost every med school. No Bio, no med school, it’s that simple.
  • MCAT gold. Biology/Biochemistry (B/B) and Chemical/Physical Foundations (C/P) sections are loaded with bio concepts.
  • Covers the essentials. We’re talking about genetics, cell biology, physiology—all the good stuff you’ll need to know inside out.

These classes lay down the groundwork for all things medical. You’ll be looking at the building blocks of life, how cells function, and what happens when things go wrong (spoiler: diseases). Everything you learn here will pop up again in med school and beyond.

General Chemistry 1 & 2: Unlocking Chemical Reactions

Next up—General Chemistry. Is it the most fun course ever? Probably not. But is it important? 

Absolutely. Think of this as the “glue” that binds together everything else you’ll learn in medicine.

Why you need it:

  • Prerequisite for most med schools. No chem, no med school.
  • High-yield for the MCAT. A lot of the Chemical/Physical section hinges on what you learn in Chem 1 and 2.
  • Key topics include: Chemical reactions, thermodynamics, bonding—essentially the building blocks for understanding drugs, treatments, and, well, life.

Think of Gen Chem as the foundation for everything you’ll dive into later, like Orgo and Biochem. Plus, you’ll use these concepts over and over in medical research and clinical settings. So, yeah, mastering it now gives you the power to tackle more advanced topics with confidence later.

Organic Chemistry 1 & 2: Understanding the Building Blocks of Life

Oh, Organic Chemistry. The course that’s infamous for causing sleepless nights for premeds. But believe it or not, it’s not just about memorizing reactions (though, yeah, there’s plenty of that). 

It’s about understanding the basic chemistry that governs living systems. And, guess what? You’ll need it for med school and beyond.

Here’s the deal:

  • Prerequisite for med schools: No Orgo, no med school.
  • Moderate MCAT value: You’ll find it in the Chemical/Physical section, but it also lays the groundwork for Biochem.
  • Why it’s essential: Organic chemistry builds the bridge between basic chemistry and biochemistry. It’s the key to understanding reactions at a molecular level, which is vital for understanding how the body processes drugs, how DNA replicates, and more.

Yes, it’s tough. But getting through Organic Chemistry will give you the tools to crush Biochem and other advanced topics later.

Chemistry

Biochemistry 1 & 2: The Chemistry of Life

Now we’re getting to the real fun stuff. Biochemistry ties together everything you learned in Biology, Chemistry, and Organic Chemistry, and it brings them into the real world of medical science. This is where you truly start thinking like a future doctor, understanding how molecules interact and influence living systems.

Why it’s a must:

  • Biochemistry 1 is required by many med schools. Some will want Biochem 2 too.
  • MCAT goldmine: Biochemistry dominates both the Bio/Biochem and Chem/Phys sections.
  • Essential concepts: Protein structure, enzyme functions, metabolism—this is where medicine really happens at the molecular level.

You’ll use this knowledge not just for the MCAT, but throughout med school and beyond. Trust me—understanding the biochemical pathways of diseases and treatments is what will make you an exceptional physician.

Physics

Physics 1 & 2: Mastering the Mechanics of Medicine

You might be scratching your head and wondering what on earth physics has to do with being a doctor. But, surprise—physics has everything to do with medicine. From understanding how the body moves to how medical imaging works, physics is crucial.

Here’s why:

  • Prerequisite for most med schools: Physics is everywhere in medicine.
  • Mid-level MCAT value: It shows up in the Chemical/Physical section.
  • Why it’s useful: You’ll need to understand topics like fluid dynamics, optics (hello, medical imaging!), and electricity (think EKGs and nerve impulses).

Mastering Physics 1 & 2 gives you a solid understanding of how physical principles apply to the human body and medical technology. Plus, when you hit those radiology rotations, you’ll be glad you paid attention.

English Composition 1 & 2: Because Writing Actually Matters

You might think writing is the least of your worries, but guess what? It matters—a lot. Whether it’s writing up research papers, crafting a personal statement, or (eventually) documenting patient notes, clear communication is key. And the sooner you sharpen your writing skills, the better off you’ll be.

Why it’s important:

  • Med school requirement: Most med schools want to see English Comp on your transcript.
  • MCAT benefit: Writing practice helps you articulate ideas, which is especially useful in the CARS section.
  • Plus: It’s essential for writing strong essays in your med school applications!

English Comp is about way more than essays—it’s about learning to communicate clearly, which is something you’ll be doing every day as a doctor. So, if you’ve been neglecting those grammar skills, now’s the time to polish them up.

Highly Recommended Courses for a Competitive Edge

Okay, so you’ve got the essentials covered. But if you want to stand out from the crowd and take your premed prep to the next level, consider adding these highly recommended courses to your schedule. They aren’t always required, but boy, do they make a difference.

Statistics: The Language of Medical Research

Ever wonder how doctors know which treatments work best? That’s where statistics comes in. Understanding how to interpret data is critical in medicine, whether you’re reading up on clinical trials or conducting your own research.

Why it’s a game-changer:

  • Required by some med schools, but helpful for all.
  • MCAT hot topic: Stats comes up in every section except CARS.
  • Why it matters: Medicine is evidence-based, and that means you’ll need to understand how to analyze data, read research, and apply it to patient care.

Take a stats class, and you’ll not only boost your MCAT score, but you’ll also be ready to crush med school research papers.

Genetics: Understanding the Blueprint of Life

Genetics is everywhere in medicine these days. From understanding genetic diseases to cutting-edge research like gene therapy, knowing the ins and outs of DNA is huge. It’s also a mid-yield topic on the MCAT, making it an important one to study.

Here’s why:

  • Mid-yield for the MCAT, especially in the Bio/Biochem section.
  • Why it’s valuable: You’ll be looking at genetic disorders, heredity, and how genes play a role in diseases. And honestly, the more you know about genetics, the better prepared you’ll be for med school.

So, if you’ve got room in your schedule, take genetics. It’s a game-changer.

Molecular Biology: Digging Deeper Into Life

If you want to get real serious about understanding life at the molecular level, Molecular Biology is where it’s at. This course takes what you’ve learned in bio and chem and drills down deeper into the molecular processes that keep us alive. It’s high-yield for the MCAT too!

Here’s the deal:

  • MCAT high-yield, especially in Bio/Biochem.
  • Why it rocks: Molecular biology explains gene expression, protein synthesis, and how cells signal each other. All things you’ll be using in med school and beyond.

Molecular Bio will make you a molecular science pro, which—let’s face it—makes you sound like a boss when it comes time for med school interviews.

Cell Biology: The Basics of Life

In med school, you’ll spend a lot of time learning how cells work. That’s why a solid understanding of Cell Biology is so important. It’s a big topic on the MCAT, and it gives you the foundation you’ll need to understand how diseases and treatments affect the body at the cellular level.

Why it matters:

  • MCAT high-yield, especially in Bio/Biochem.
  • Why you should care: Cells are the basic units of life, and understanding how they work is crucial for everything from diagnosing diseases to developing treatments.

It’s simple—know your cells, know your medicine.

Microbiology: The World of Invisible Invaders

If you’re interested in infectious diseases (and let’s be honest, they’re kind of a big deal these days), Microbiology is a must. 

You’ll be studying bacteria, viruses, and all those other tiny organisms that wreak havoc on the body. While it’s not a huge focus on the MCAT, it’s super relevant to the world of medicine.

Why it’s useful:

  • Low-yield on the MCAT, but still highly relevant.
  • Why you should care: Microbes are involved in almost every illness, from the flu to COVID-19. If you plan to work in fields like immunology or epidemiology, this is your jam.

Microbiology will give you a leg up in understanding how to tackle infectious diseases head-on.

Optional Courses to Consider: If You’ve Got Room in Your Schedule

Alright, so you’ve knocked out the essentials and highly recommended courses. If you’ve still got room, here are a few optional courses that could give you an extra edge. They aren’t required, but they might just make your med school life a little easier.

Psychology and Sociology: Understanding Human Behavior

These courses are super relevant for medicine because you’re going to be working with people. Understanding how the human mind works and how society influences behavior will help you become a more empathetic and effective doctor. Plus, they’re high-yield on the MCAT.

Why they’re worth it:

  • MCAT high-yield: Big deal in the Psych/Soc section.
  • Plus: They often count as Humanities credits, so you can kill two birds with one stone.

Having a good grasp of Psych and Soc can help you connect with patients on a deeper level, and that’s something med schools love to see.

Ethics: Because Medicine Isn’t Just Science

Ethics is a huge part of medicine. You’ll be faced with tough decisions throughout your career, and knowing how to handle them with grace and professionalism is key. It’s also super useful for prepping for CASPer and MMIs during your med school application process.

Why it’s valuable:

  • CASPer and MMI prep: Ethics questions come up a lot in interviews.
  • Why you should care: Ethical dilemmas happen all the time in medicine, and knowing how to navigate them is a huge part of being a good doctor.

Taking an ethics course will help you think critically about the tough decisions you’ll face in the future.

Medical Terminology: Speak Like a Doctor

Medical Terminology might not be on the MCAT, but it’s incredibly useful once you get to med school. You’ll be swimming in new terms, and having a basic understanding beforehand will make your life a lot easier.

  • Not MCAT-tested, but essential for med school.
  • Why you should care: Learning medical lingo now will save you time and stress later.

Knowing your medical terms means you won’t be playing catch-up when you start hearing fancy words like “sphygmomanometer” thrown around.

English

Start Practicing CARS Early!

CARS (Critical Analysis and Reasoning Skills) is a beast of its own. Unlike other sections of the MCAT, it’s not about content knowledge—it’s about your ability to read, analyze, and understand complex passages. And since you’re not learning this stuff in your regular premed classes, you’ll need to practice on your own.

Why it’s important:

  • MCAT section: CARS is its own thing, and it can be tricky.
  • The secret: Start practicing early! Do one passage a day to build your skills gradually.

By the time MCAT season rolls around, you’ll be a CARS master.

Conclusion: Make a Plan for Success

There you have it—the best premed undergrad courses to maximize your med school chances. Whether it’s the must-take science courses, the highly recommended ones that’ll give you an edge, or the optional courses that can help you shine, building a solid course schedule is key to your success. You got this, future doc!
