Advanced Placement (AP®) and International Baccalaureate (IB) courses are college-level classes taken during high school. They demonstrate academic rigor, prepare you for the pace and depth of college coursework, and in some cases provide college credit that allows you to skip introductory courses. For students interested in pre-med, the question is not whether to take AP®/IB courses but which ones to prioritize and how many to take without overwhelming yourself. This page covers the most relevant AP® and IB courses for pre-med, how college credit works, and common mistakes to avoid.
The Most Relevant AP Courses for Pre-Med
AP® Biology: The single most relevant AP® course for pre-med students. It covers cell biology, genetics, evolution, ecology, and anatomy at a depth that directly prepares you for college-level biology. A strong AP® Biology score (4 or 5) may earn you college credit that allows you to skip introductory biology, though many pre-med advisors recommend retaking introductory biology in college regardless to build a stronger foundation for the MCAT®.
AP® Chemistry: Highly relevant for pre-med. Covers atomic structure, bonding, thermodynamics, kinetics, equilibrium, and electrochemistry. General chemistry is a prerequisite for organic chemistry in college, which is one of the most challenging pre-med courses. A strong AP® Chemistry foundation makes college chemistry significantly easier. As with biology, some pre-med advisors recommend retaking general chemistry in college even with AP® credit.
AP® Physics (1, 2, or C): Physics is a required pre-med prerequisite. AP® Physics 1 covers mechanics (forces, energy, momentum), and AP® Physics 2 covers electricity, magnetism, optics, and modern physics. AP® Physics C is calculus-based and is more appropriate for students who have completed or are concurrently taking calculus. For pre-med purposes, AP® Physics 1 and 2 (algebra-based) are sufficient, though Physics C provides a stronger foundation.
AP® Calculus (AB or BC): While calculus is not a pre-med prerequisite at most medical schools, it is required or recommended at some, and it strengthens your quantitative reasoning. AP® Calculus AB covers the equivalent of one semester of college calculus; BC covers two semesters. Strong math skills are essential for physics, chemistry, and the quantitative reasoning sections of the MCAT®.
AP® Psychology: Psychology is one of the four sections of the MCAT® (Psychological, Social, and Biological Foundations of Behavior). AP® Psychology provides a strong introduction to the content tested on this section. It is also a relatively manageable AP® course, making it a good option for students who want to add rigor without excessive workload.
AP® Statistics: Statistics is increasingly important in medicine (evidence-based practice, interpreting research, understanding clinical trials) and is tested on the MCAT®. AP® Statistics covers data analysis, probability, and statistical inference at a level that prepares you well for college statistics and for the biostatistics content on the MCAT®.
IB Courses for Pre-Med
If your school offers the International Baccalaureate program, the most relevant Higher Level (HL) courses for pre-med are Biology HL, Chemistry HL, Physics HL, and Mathematics HL. IB HL courses cover content at a depth comparable to AP® courses, and scores of 6 or 7 on HL exams are typically accepted for college credit at most universities. Standard Level (SL) IB courses are less likely to earn college credit but still demonstrate academic rigor. The same advice applies: choose the courses that align with your strengths and interests, and do not overload yourself to the point where your grades suffer.
The College Credit Question
Here is a nuance that many high school students miss: earning AP® or IB credit does not always mean you should use it to skip college courses. Many pre-med advisors recommend retaking introductory biology, general chemistry, and physics in college even if you have AP® credit, because medical school admissions committees want to see college-level science performance, the college versions of these courses often cover material in greater depth than AP®, and a strong college science GPA is more important for your medical school application than saving one or two semesters.
The exception is when your AP® credit places you into a higher-level course (AP® Biology credit lets you start with Genetics or Molecular Biology instead of Intro Biology) and you perform well at that higher level. This demonstrates advanced ability and can impress admissions committees. The decision depends on your individual preparation, your college’s specific policies, and advice from your pre-health advisor. See our pre-med requirements page for how prerequisites work at the college level.
How Many AP/IB Courses Should You Take
There is no magic number. The right number of AP®/IB courses depends on your school’s offerings, your academic strengths, your other commitments (extracurriculars, work, family responsibilities), and your ability to maintain strong grades while taking rigorous courses. A general guideline for competitive college applicants: 1 to 2 AP® courses in 10th grade, 2 to 4 in 11th grade, and 2 to 4 in 12th grade, for a total of 5 to 10 over high school. Students at schools that offer fewer AP® courses are not penalized; colleges evaluate your course selection in the context of what your school offers. Taking the most challenging courses available at your school, whatever those are, demonstrates the rigor that colleges want to see.

AP Courses That Are Less Directly Relevant (But Still Valuable): AP® English Language and AP® English Literature develop the writing and analytical skills you need for college essays, personal statements, and eventually clinical documentation. AP® History courses (U.S. History, World History, European History) build critical reading, evidence-based argumentation, and the ability to synthesize large amounts of information, all skills that transfer to medical education. AP® Computer Science is increasingly relevant as technology transforms healthcare. AP® Spanish or another AP® Foreign Language strengthens your ability to communicate with diverse patient populations. None of these courses are pre-med prerequisites, but they contribute to a well-rounded education and demonstrate intellectual breadth.
Managing the AP Exam: Preparing for AP® exams requires a study plan that begins well before the May testing window. Use free AP® review resources first: College Board provides free AP® practice exams and course materials on their website, and Khan Academy® offers free AP® review content for many subjects. Study groups with classmates can be highly effective for AP® exam preparation. Your teacher is your best resource; attend any review sessions they offer. On exam day, manage your time carefully (practice with timed exams beforehand), read each question fully before answering, and remember that earning a 3 or above is considered passing, a 4 is strong, and a 5 is excellent. See our standardized test prep page for general test preparation strategies.
Self-Studying for AP Exams: If your school does not offer a particular AP® course, you can self-study for the AP® exam. The College Board allows students to register for any AP® exam, even without taking the corresponding course. Self-studying is most feasible for content-heavy courses like AP® Psychology, AP® Environmental Science, or AP® Human Geography. Self-studying for lab-based courses like AP® Chemistry or AP® Biology is more challenging because the lab component is difficult to replicate independently. If you self-study, use the College Board’s official course materials, free online resources, and practice exams to prepare.
