Colorado Pre-Med Timeline

A year-by-year guide for Colorado pre-med students — from freshman year through AMCAS Match Day. Includes Colorado-specific deadlines, AMCAS strategy, and how to navigate both application systems simultaneously.

Colorado Application Key Dates

Mid-March

AMCAS Match Day — Colorado public school decisions released

April 30

Deadline to hold multiple acceptances (AAMC traffic rules)

Dr. Tomei's Perspective

The single most important date for Colorado pre-meds is May 1 — the day AMCAS opens. I have seen students lose their entire application cycle because they submitted AMCAS in July instead of June. Colorado schools review applications on a rolling basis, and the early spots fill fast. Treat May 1 like a deadline, not an opening.

Year-by-Year Pre-Med Timeline

Freshman Year

Build the Foundation

Choose your major — biology, biochemistry, or any major you will excel in. Medical schools do not require a specific major.

Join your university's pre-med organization (CU Boulder Pre-Med Society, CSU Pre-Med Club, DU Pre-Health Society, etc.) for advising resources and peer support.

Start volunteering at a local hospital, free clinic, or community health center. Even 4–6 hours per month builds meaningful experience over four years.

Introduce yourself to your pre-med advisor and understand your university's pre-med requirements.

Take General Biology and General Chemistry — the foundation of your science GPA.

Explore research opportunities. Many Colorado universities have freshman research programs (CU Boulder UROP, CSU Undergraduate Research Program, DU Research Scholars).

Attend pre-med information sessions to understand the AMCAS and AACOMAS timelines.

Colorado-Specific: Colorado public universities have strong pre-med advising offices. Use them early and often. University of Colorado, Colorado State University, and University of Denver all have dedicated pre-health advising staff who know AMCAS inside and out.

Sophomore Year

Build Clinical Experience and Begin MCAT Prep

Continue and expand clinical volunteering — aim for 50+ hours by end of sophomore year.

Begin physician shadowing — cold-email physicians in your area or leverage your university's shadowing programs.

Take Organic Chemistry and Physics — the most challenging pre-med prerequisites for most students.

Begin thinking about MCAT prep. The MCAT covers material through Biochemistry and Psychology/Sociology — plan your coursework accordingly.

Pursue research if you have not already. Colorado medical schools — especially the University of Colorado School of Medicine — value research experience.

Consider joining a pre-med honor society (Alpha Epsilon Delta) for networking and advising resources.

Attend AMCAS information sessions — many Colorado universities host these in the fall.

Colorado-Specific: If you are at a Colorado university, your pre-med advisor will have specific guidance on AMCAS requirements. Ask about the Colorado residency requirement and make sure you understand what qualifies as Colorado residency for AMCAS purposes.

Junior Year

MCAT, Applications, and Letters of Recommendation

Take the MCAT in the spring (March–May) to have scores before application season opens.

AMCAS opens May 1 — submit by June 1 for best chances. Early submission is critical for Colorado schools.

AMCAS opens June 1 — submit as early as possible after opening.

Request letters of recommendation in the spring semester — give recommenders at least 6–8 weeks.

Write your personal statement — start drafts in February or March.

Write AMCAS school-specific essays — each Colorado school has separate prompts.

Complete your activity list for both AMCAS and AACOMAS.

Secondary applications arrive July–September — respond within 2 weeks of receipt.

Interview invitations arrive August–November.

Colorado-Specific: AMCAS has a unique "rolling" review process — the earlier you submit, the earlier your application is reviewed. Submitting on May 1 (opening day) gives you the maximum advantage. Do not wait until June or July to submit AMCAS. AMCAS verification takes 4–6 weeks after submission, so submit AMCAS as early as possible in June.

Senior Year

Interviews, Decisions, and Waitlists

Interviews run September through February — prepare for both traditional and MMI formats.

AMCAS Match Day is in mid-March — Colorado public schools use a matching algorithm, not rolling admissions.

AMCAS schools send acceptances on a rolling basis starting October 15.

If waitlisted, send a letter of continued interest in April or May.

Accept your offer and submit your deposit by the deadline.

Complete any remaining prerequisites if needed.

Prepare for medical school — review biochemistry, anatomy, and physiology over the summer.

Colorado-Specific: The AMCAS Match is unique to Colorado. Unlike AMCAS schools that send individual acceptances, Colorado public schools participate in a centralized match where you rank your preferred schools and they rank you. Understanding how the match algorithm works — and how to rank your schools strategically — is critical. Do not rank schools based on prestige alone.

Running AMCAS and AACOMAS Simultaneously

Most Colorado pre-meds applying to medical school use AMCAS for MD programs and AACOMAS for DO programs. If you are applying to both, you need to manage two separate application systems simultaneously. This is one of the most logistically complex aspects of applying to medical school as a Colorado resident.

The key is to treat them as two separate applications that happen to share some content. Your personal statement can be adapted for both systems, but the AMCAS school-specific essays are entirely separate from AMCAS secondary essays. You will need to write unique content for each Colorado school through AMCAS in addition to your AMCAS secondaries.

Budget your time accordingly. In the spring of your junior year, you should be working on your personal statement, your AMCAS school-specific essays, your AMCAS activity list, and your letters of recommendation simultaneously. This is a significant workload — start early.

Dr. Tomei's Perspective

The students who struggle most with the Colorado application process are the ones who treat AMCAS and AACOMAS as sequential tasks — finish one, then start the other. That approach will get you to July or August before you have submitted both applications, and by then you have already lost your early advantage at Colorado schools. Work on both simultaneously. It is more work, but it is the only way to be competitive.
