Oregon Health & Science University School of Medicine prerequisites

2 semesters · 8 credits · lab

Two semesters with lab. The single most universal prerequisite: essentially every MD and DO program asks for it, and it is the foundation the MCAT assumes.

2 semesters · 8 credits · lab

Two semesters with lab. Take it early: organic chemistry, biochemistry, and most upper-division biology all sit behind it, so a late start pushes the whole sequence past your MCAT date.

2 semesters · 8 credits · lab

Two semesters with lab at most schools. A meaningful and growing minority accept one semester of organic plus one of biochemistry. Do not drop the second semester on that assumption until you have checked the schools you actually want.

1 semester · 3 credits

One semester, lab rarely required. Roughly two thirds of schools require it outright and the MCAT tests it heavily, so treat it as required even where it technically is not, and take it before you sit the exam.

2 semesters · 8 credits · lab

Two semesters with lab. Algebra-based is accepted almost everywhere; take the calculus-based sequence only if your major needs it or a target school names it.

2 semesters · 6 credits

Two semesters of English or writing-intensive coursework. Many schools accept writing-intensive courses from any department, but a few name English specifically. If your writing credits come from elsewhere, confirm before you count them.

1 semester · 3 credits

One semester. Most schools with a math requirement accept statistics or calculus; statistics is the more widely accepted of the two and the more useful for reading clinical research, so the baseline tracks it here. If a target school names calculus, its own requirements will say so.

1 semester · 3 credits

One semester. Required outright at a minority of schools (several of them highly selective) and accepted in place of statistics at most of the rest. Take it if calculus is already in your major's path.

1 semester · 3 credits

One semester. A minority of schools require it, but a quarter of the MCAT is psychological and social foundations: this is the cheapest points on the exam.

1 semester · 3 credits

One semester. Same reasoning as psychology: required by fewer schools, tested directly on the MCAT.

1 semester · 3 credits

One semester. Required by a small number of schools and a common way to fill the upper-division science coursework that strengthens a science GPA.

150+ hours

OHSU gives "strong preference" to applicants with "significant experiences in health care, leadership, extracurricular activities and/or community service", and looks for an "understanding and appreciation of health care issues and/or biomedical research". It publishes no hours figure, and its stated interest in rural health, underserved areas and primary care is the lens those experiences get read through.

50+ hours

Aim for 40-50 across more than one specialty, including primary care. DO programs weigh shadowing more heavily and several ask for hours with a DO specifically. If DO schools are on your list, get those hours and the letter early.

150+ hours

Service with no medical angle. Committees are reading for a habit, not a total, so one commitment held for two years beats five one-off events.

100+ hours

Effectively expected at research-heavy MD programs and genuinely optional at many DO and community-focused schools. If research is not your path, put those hours into clinical work and say so clearly rather than padding a semester in a lab.

No published minimum

"If you choose to, you can submit a packet of at least three individual faculty letters or a premedical committee evaluation report (committee letter) instead of three separate recommendations." All letters must go through the AMCAS Letter Service; OHSU will pull from VirtualEvals or Interfolio through AMCAS.

3 letters

"We require letters from three college or university teaching faculty from any department, with at least one from teaching faculty in a science department." Only one of the three must be a science professor; the other two may be from any department.

No published minimum

"If you have been out of college for five years or more, you can submit two letters from employers and one from a teaching faculty member." OHSU also "encourages you to submit a well-chosen group of letters, including nonacademic recommendations that highlight your experiences in health care/physician shadowing and your extracurricular accomplishments." There is no maximum.
