The most valuable things to study before medical school aren’t dense textbooks. They’re the foundational sciences you’ll see on day one, the medical vocabulary that makes those sciences accessible, and the study techniques that will keep you afloat once the firehose of information turns on. Getting familiar with these areas before orientation gives you a genuine head start without burning out before classes begin.
Anatomy and Physiology Come First
Your first year of medical school is built almost entirely on understanding the human body’s structure and function. At Vanderbilt, for example, the M1 year moves through six sequential blocks: human anatomy and architecture, microbes and immunity, homeostasis, renal and digestion, reproduction and endocrine, and brain, behavior, and movement. Other schools follow a similar pattern. Everything flows from knowing how the body is built and how its systems talk to each other.
If you had to pick one subject to review, make it anatomy. Certain regions come up repeatedly on board exams and in clinical practice. The cranial nerves, spinal cord pathways, and coronary artery anatomy are consistently high-yield. Embryology also features heavily, particularly germ layer derivatives (which tissues come from which early cell layers), kidney development, GI development, and the branchial apparatus, which gives rise to structures in the head and neck. You don’t need to memorize every detail now, but building a mental scaffold of these areas means you’ll absorb lectures faster when they arrive.
Physiology pairs naturally with anatomy. Understanding how the heart generates its electrical rhythm, how the kidneys filter blood, or how neurons transmit signals gives you context that pure memorization can’t. If you took these courses in undergrad, a focused review of your old notes or a physiology textbook will refresh enough to matter. If you didn’t, even watching a solid YouTube series on organ system physiology will put you ahead.
Learn Medical Terminology Early
Medical language looks intimidating, but it follows predictable rules. Most terms are assembled from Greek and Latin roots, prefixes, and suffixes. Once you know the building blocks, you can decode words you’ve never seen before.
Take “cardiomyopathy.” Break it apart: “cardio” means heart, “myo” means muscle, “pathy” means disease. Heart muscle disease. Or consider how a single prefix changes meaning: “pericarditis” is inflammation of the outer heart layer, while “endocarditis” is inflammation of the inner lining. The suffix matters too. A “cardiologist” is a heart specialist, while “cardiomegaly” means enlargement of the heart.
Spending a few weeks with a medical terminology resource before school starts pays off immediately. You’ll understand lecture slides faster, read textbooks more fluidly, and spend less mental energy translating language when you should be learning concepts. Des Moines University offers a free online medical terminology guide that covers the essential roots, prefixes, and suffixes systematically.
Biochemistry and Cell Biology
These two subjects underpin nearly everything in the first-year curriculum, from how drugs work to how diseases develop at the molecular level. You’ll revisit metabolic pathways like glycolysis and the citric acid cycle repeatedly. Cell signaling, DNA replication, and protein synthesis show up in immunology, pharmacology, and genetics coursework.
If your undergrad biochemistry feels hazy, reviewing the major metabolic pathways and understanding how enzymes regulate them is time well spent. You don’t need to memorize every intermediate. Focus on the logic: why the pathway exists, what happens when it fails, and which organs depend on it most. That conceptual understanding transfers directly to clinical reasoning later.
Master Study Techniques, Not Just Content
Here’s something most incoming students underestimate: how you study matters more than what you pre-study. Medical school delivers an extraordinary volume of information, often covering in one week what an undergraduate course covers in a month. The students who struggle most aren’t usually the ones with the weakest science backgrounds. They’re the ones still using passive strategies like re-reading notes and highlighting textbooks.
Six learning strategies have strong research support in the psychology literature, and all of them apply directly to medical education:
- Spaced practice: distributing your studying over multiple days rather than cramming the night before. Reviewing material at increasing intervals dramatically improves long-term retention.
- Retrieval practice: testing yourself on material rather than passively re-reading it. Flashcard apps like Anki are built on this principle and are wildly popular among medical students for good reason.
- Interleaved practice: alternating between different topics in a single study session rather than spending hours on one subject. This forces your brain to distinguish between concepts and strengthens understanding.
- Elaboration: connecting new information to things you already know. When you learn a new disease process, linking it to the normal physiology you already understand makes both stick.
- Dual coding: combining words with visuals, like drawing diagrams of pathways while explaining them out loud.
- Concrete examples: grounding abstract principles in specific clinical scenarios to make them memorable.
Learning to use Anki effectively before school starts is one of the highest-return investments you can make. Many students spend weeks figuring out the software and building a workflow while simultaneously drowning in new material. Getting comfortable with spaced repetition flashcards during the summer means one less thing to figure out in August.
Get Comfortable With Clinical Basics
Medical schools introduce patient interaction earlier than most students expect. You’ll likely begin learning to take a patient history in your first semester. A standard history follows a consistent structure: the patient’s current complaint, their medical history, past surgeries, family medical history, social history (things like occupation, living situation, smoking, alcohol use), allergies, and current medications.
You don’t need to practice on patients before school. But reading through a guide to history-taking, like the relevant chapters from Bates’ Guide to Physical Examination, familiarizes you with the framework so the first standardized patient encounter feels less foreign. Understanding what information you’re trying to gather, and why, gives clinical skills sessions more meaning from the start.
Ethics and Professionalism
Medical ethics appears in your curriculum from week one and stays through board exams. The core framework rests on four principles: beneficence (acting in the patient’s best interest), nonmaleficence (avoiding harm), autonomy (respecting a patient’s right to make their own decisions), and justice (distributing care fairly). These four pillars come up in case discussions, exam questions, and eventually in real clinical dilemmas during rotations.
Reading a short introduction to medical ethics before school helps you engage more meaningfully in early discussions. These aren’t abstract philosophical exercises. They shape how you’ll navigate situations like a patient refusing treatment, families disagreeing about care, or resources being limited.
What Not to Do Before Medical School
Pre-matriculation programs at medical schools have shifted away from trying to fill content gaps before classes start. Research published in Medical Science Educator found that programs focused exclusively on scientific knowledge were ineffective at bridging academic gaps. The programs that actually helped students succeed focused on professional development, wellness, and teaching students how to approach learning in medical school rather than drilling specific content.
That finding carries a practical lesson: don’t try to pre-learn your entire first-year curriculum over the summer. You’ll cover it all again in far more depth and with better resources once school begins. The goal of pre-studying isn’t mastery. It’s familiarity. You want the first time you hear “brachial plexus” or “glomerular filtration rate” to be the second time, not the first. That small edge compounds across thousands of new terms and concepts.
Rest matters too. Medical school is a four-year marathon with clinical rotations, board exams, and residency applications stacked on top of each other. Starting well-rested, with strong study habits and a light scaffold of foundational knowledge, puts you in a better position than starting exhausted with a head full of half-memorized facts.
