University of Colorado 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 of the few things Colorado states outright: a basic understanding of statistics or biostatistics is required to handle the quantitative side of medicine and biomedical research.

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

Named explicitly among the additional coursework Colorado encourages, alongside biochemistry and computer science.

1 semester · 3 credits

One of the four competency areas is the humanistic understanding of patients as individuals and members of families, communities, and society. Humanities and social science coursework is how most applicants evidence it.

150+ hours

Almost no school publishes a number, but admitted applicants typically report a few hundred hours. 150 is the point where you can speak about patient care from experience rather than in the abstract; sustained hours over years read better than a summer sprint.

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

"We require three to five letters, or a committee summary letter... A committee letter is sufficient to meet the medical school letter of recommendation requirements." All letters must go through AMCAS.

No published minimum

"Research experience" is one of the four sources Colorado names for its three to five letters, alongside faculty, clinical experience, and a current job.

No published minimum

Colorado's letters "can come from a faculty member, clinical experience, research experience, or a current job as the letter transmits cogent information about the applicant's work. Obtaining a letter from the employer who you are working with during the application year is highly recommended."
