Junior year is the most consequential year of your pre-med career. You take the MCAT, build your school list, request letters of recommendation, and begin drafting your personal statement. Everything you have done since freshman year converges here.
Fall semester priorities
Complete remaining prerequisites. Finish any MCAT prerequisite courses you have not yet taken (biochemistry, physics II, sociology). Every prerequisite completed before MCAT prep begins is one less subject you need to learn from scratch.
Request letters of recommendation. You need 3-5 letters for medical school: two from science professors who know you well, one from a non-science professor, and one from a physician or research mentor. Ask in person, explain why you are asking them specifically, and provide a “brag sheet” (a one-page summary of your GPA, activities, research, clinical hours, and goals). Give each writer at least 6-8 weeks before the deadline.
Begin your school list research. Use the AAMC MSAR (Medical School Admission Requirements) database ($28 for a one-year subscription, worth every dollar). Create a spreadsheet with: school name, location, median GPA, median MCAT, mission statement, and any unique programs that match your background. Aim for an initial list of 25-30 schools.
MCAT preparation
The MCAT is a 7.5-hour exam testing four areas: Chemical and Physical Foundations, Critical Analysis and Reasoning (CARS), Biological and Biochemical Foundations, and Psychological, Social, and Biological Foundations. Your target score depends on your school list, but a 510+ (80th percentile) is competitive for most MD programs, and a 506+ (70th) for most DO programs.
Study timeline: 3-6 months of dedicated preparation. Most students study 6-8 hours per day for 3 months (full-time summer prep) or 2-3 hours per day for 5-6 months (part-time during the school year). Choose the approach that fits your schedule and personality.
Free and low-cost resources: AAMC official practice materials (4 full-length practice exams, section bank, question packs; approximately $200 total but these are essential), Khan Academy MCAT prep (free, comprehensive video library covering all tested content), Anki MCAT decks (free flashcard sets created by previous test-takers; search “MilesDown” or “JackSparrow” decks), and free practice exams from test prep companies (use for additional practice after completing AAMC materials).
When to take it: Most students take the MCAT in May, June, or July between junior and senior year. This allows scores (released 4-5 weeks after the test) to be available when AMCAS opens in late May. If you take it in January or March, you have time to retake if needed before the application cycle.
Spring semester: personal statement
Start drafting your personal statement in January or February. This is a one-page (5,300 characters) essay answering one question: why do you want to be a physician? Not a healthcare worker, not a researcher, not a PA. A physician specifically.
The best personal statements are not about a single dramatic moment. They weave together multiple experiences that show a pattern of growth, reflection, and commitment. See our Personal Statement Guide for a framework and common pitfalls.
Write a rough draft. Let it sit for two weeks. Revise. Get feedback from 3-5 readers (your pre-health advisor, a professor, a friend who writes well, a physician mentor). Revise again. Repeat until you have a polished essay by April.
Clinical and research milestones
By the end of junior year, aim for: 200+ clinical hours (paid or volunteer), a defined research project with potential for a poster or publication, 100+ hours of non-clinical community service, and at least one leadership position you have held for 1+ years.
These are not rigid requirements. They are benchmarks that make you competitive at most MD programs. DO programs may weight clinical experience and community service more heavily than research.
