Premed is not a major or a degree. It’s a track, meaning a set of courses, experiences, and milestones you complete during college to qualify for medical school. You can be premed while majoring in anything from biology to English, as long as you finish the required prerequisite courses and build the clinical profile that admissions committees expect. The path typically takes four years of undergraduate work, followed by four years of medical school.
What Premed Actually Means
When someone says they’re “premed,” they mean they’re planning to apply to medical school and are structuring their college experience around that goal. Some universities have a formal premed advising program or a premed track within the biology department, but there is no standardized premed degree. You declare a major of your choice and layer on the science prerequisites, extracurricular clinical work, and standardized testing that medical schools require.
This distinction matters because it gives you flexibility. Medical schools set their own admission requirements, and those requirements focus on specific courses and competencies rather than a particular diploma.
Prerequisite Courses
Every medical school publishes its own list of required coursework, but most overlap heavily. The core prerequisites you’ll see at nearly every MD and DO program include:
- Biology: Two semesters (roughly 8 credit hours), usually with labs. Some schools specify topics like genetics, cell biology, or anatomy and physiology.
- General chemistry: Two semesters with labs.
- Organic chemistry: One to two semesters with labs. Many schools also require or recommend biochemistry.
- Physics: Two semesters with labs.
- English or writing: Two semesters. Some schools accept writing-intensive courses from other departments, such as philosophy or history.
- Math or statistics: One to two semesters, which may mean calculus, statistics, or biostatistics depending on the school.
- Psychology and sociology: Frequently required or strongly recommended, partly because these subjects appear on the MCAT.
A few practical notes: policies on Advanced Placement credit vary by school. Some accept AP scores to satisfy prerequisites, while others want you to take upper-level coursework in that subject instead. Community college courses and online courses are accepted at many schools, but not all. Check the specific requirements for every school on your list rather than assuming a single checklist covers them all. The AAMC’s Medical School Admission Requirements (MSAR) database is the most reliable place to look up each school’s policies.
You Can Major in Anything
Most premed students major in biological sciences, but you don’t have to. AAMC data from the 2023-2024 admissions cycle shows that applicants came from a wide range of undergraduate majors, and students outside the sciences were accepted at comparable rates. Humanities majors, for example, made up a smaller applicant pool (1,661 applicants) but roughly 52% matriculated into medical school. Social science majors saw about 43% of their 4,844 applicants matriculate. Biological sciences, the most popular major by far with over 30,000 applicants, had a matriculation rate of about 43% as well.
The takeaway: your major does not make or break your application. What matters is that you complete the prerequisite courses with strong grades and perform well on the MCAT. Choosing a major you genuinely enjoy can actually help, since a higher GPA in a subject you care about is better than a mediocre GPA in one you picked because it “looked premed.”
The MCAT
The Medical College Admission Test is a standardized, computer-based exam divided into four multiple-choice sections: Biological and Biochemical Foundations of Living Systems, Chemical and Physical Foundations of Biological Systems, Psychological Social and Biological Foundations of Behavior, and Critical Analysis and Reasoning Skills. Total scores range from 472 to 528, with 500 as the midpoint.
The exam is long (over seven hours including breaks) and tests both scientific knowledge and reasoning ability. Most students study for three to six months, dedicating at least 10 to 15 hours per week. Many take the exam the summer before senior year, though some take it earlier if they feel ready. Your MCAT score and your GPA are the two most important quantitative factors in your application.
Clinical Experience and Volunteering
Strong grades and a good MCAT score get your application read. Clinical experience is what shows admissions committees you actually understand what a career in medicine looks like. Medical schools expect to see several types of hands-on involvement.
Clinical volunteering means working in a healthcare setting where you interact with patients, such as a hospital, free clinic, or hospice. Around 200 hours is a solid benchmark, built steadily over one to two years rather than crammed into a single summer. A regular four-hour weekly shift over a full calendar year gets you close to that number.
Non-clinical volunteering is community service outside of healthcare: tutoring, food banks, mentoring programs. Another 200 hours in this category rounds out your profile and shows you care about service beyond the medical context.
Shadowing means observing a physician during their workday. Unlike volunteering, shadowing can be sporadic. Aim for 25 to 50 hours across multiple specialties so you can speak knowledgeably about what different doctors do.
Hours matter less than consistency and reflection. Schools conduct holistic reviews and want to see that you grew from these experiences, not just that you logged time. Applicants with fewer volunteer hours but significant work experience or extenuating circumstances are not automatically at a disadvantage.
Research and Extracurriculars
Research experience is not universally required, but it strengthens your application, especially at research-oriented medical schools. Many premed students spend a summer or a semester working in a faculty lab, and some continue for a year or more. A published paper or a poster presentation at a conference adds weight, though admissions committees also value the process itself: forming hypotheses, collecting data, and thinking critically about results.
Beyond research, schools want to see leadership and sustained commitment. This could be leading a campus organization, holding a job that required responsibility, or running a community health initiative. Depth in a few activities is more impressive than a long list of one-semester commitments.
The Application Timeline
Applying to medical school is a process that stretches over a full year, and planning should start at least two years before your target enrollment date. Here’s a general sequence for someone applying during their senior year of college:
- Spring of junior year: Begin MCAT prep with a structured study schedule.
- Summer before senior year: Take the MCAT. Start drafting your personal statement.
- Early June of senior year: Submit your primary application through AMCAS (for MD schools) or AACOMAS (for DO schools). Submitting on or near the opening date matters. AAMC data shows that 43% of applicants submit between June and July, and early submission improves your chances of early review.
- June through August: Medical schools send secondary applications, which are school-specific short essays. Returning these within 7 to 14 days signals organization and genuine interest.
- Fall and winter: Interview invitations arrive on a rolling basis. Interviews may continue through the winter months.
- January through April: Schools release admissions decisions, also on a rolling basis. Some offers come as early as January, others as late as April.
Because admissions are rolling, earlier applicants generally have an advantage. Every week you delay submission is a week more seats may be provisionally filled.
Gap Years Are Common
Not everyone applies during senior year. A growing number of applicants take one or two gap years between college and medical school to strengthen their applications. Gap years give you time to boost clinical hours, complete research, retake the MCAT if needed, or gain work experience. Medical schools view gap years neutrally or positively, especially if you use the time productively. Some applicants work as medical scribes, research coordinators, or EMTs during this period.
How Much It Costs
The premed path has real costs beyond tuition. MCAT registration alone runs several hundred dollars, with additional fees for score reports and rescheduling. The AMCAS primary application charges a base fee for the first school and an additional fee for each school you add, and most applicants apply to 15 or more programs. Secondary application fees typically range from $50 to $150 per school. Interview travel, if in person, adds further expense. The AAMC offers a Fee Assistance Program for applicants who qualify based on income, which reduces MCAT and AMCAS costs significantly.
Planning for these expenses early, ideally starting freshman or sophomore year, helps avoid financial stress during the application cycle itself.
