Applying through AMCAS and AACOMAS: how to organize both application cycles

One overview, distinct requirements

When you apply to both MD and DO programs, it is useful to see the work together. Your writing time, follow-ups and available evenings all belong to the same week. But a shared plan should not flatten the differences between application services or individual schools.

This guide focuses on organizing the work. It does not compare the professions, recommend a school list or replace either service’s application instructions. Some programs use other application routes; verify the service for the exact program rather than assigning one based only on its degree label.

AACOM describes AACOMAS as the centralized service for participating US osteopathic medical schools and directs applicants to current application instructions and college information. For AMCAS-participating programs, use the AAMC’s official resources alongside each school’s own instructions.

Give every school an identifiable record

Start with the free tracker linked above. For each school, enter the exact program, application service, official source and date checked. Keep official dates separate from personal targets. Include a next action and the system in which that action must happen.

A task label such as “Check the secondary prompt in Harbor’s portal” is more useful than “MD applications.” The former tells you where to go and what to establish. The latter asks you to rediscover the next step each time.

If you use a separate task list, connect it to the school record instead of copying the same changing deadline into several places. Review any linked dates when an invitation or instruction changes.

Separate the stages of each application

Use distinct fields or tasks for your primary application, letters, supplemental work, tests or other requirements where applicable, and interviews. These are organizational categories, not a claim that every school requires the same components.

Work area	Keep together in your plan	Verify separately
Writing	Your own experience notes and available drafting time	Current prompts, limits and school policies
Letters	Your follow-up schedule and status notes	Required types, submission route and receipt
Deadlines	A single view of upcoming work	What each deadline covers and the time zone
Costs	A running record of payments and planned expenses	Current fees, waivers and each school’s instructions

The AAMC deadlines resource concerns regular MD programs at participating schools. A primary deadline should not be treated as a universal deadline for every component. Recheck the relevant program’s instructions when making a submission decision.

Reuse the underlying experience, then answer the new question

Your experiences do not become different memories because the application system changes. A story bank can help you find your own notes about service, research, work or learning. It should not become a collection of paragraphs you paste into every school’s response.

Read the current prompt, decide which part of the experience is relevant and draft to that question. Recheck the limit and the school’s writing policies. Keep school-specific names and references attached to the correct draft so a revision for one program does not accidentally overwrite another.

Use the story bank guide to organize material before drafting. When several secondaries arrive, the prioritization guide can help you compare the actual next actions.

Plan across both systems using the same time budget

Do not give one application system Monday’s available hour and quietly give that same hour to the other. First record the time you have, then compare confirmed deadlines, dependencies and task estimates across all the schools you are managing.

For example, a fictional week might contain a near-due secondary review, a letter follow-up and a less urgent essay outline from different programs. They can share one plan while keeping their submission destinations separate. That gives you a way to choose today’s work without pretending the underlying requirements are interchangeable.

If an evening disappears, remove that availability and review what no longer fits. Rescheduling is useful only when the remaining work has a real place before its deadlines.

Close the loop in the right system

A task marked complete in your planner is your record of the action, not proof that the receiving service or school has accepted it. Save appropriate confirmations, check receipt where relevant and record the next verification step.

For letters in particular, use the service and school instructions rather than assuming receipt transfers between systems. For a specific missing step, follow the recommendation-letter guide.

End your weekly review by checking both systems for new messages and reconciling your plan. You are aiming for one reliable overview of your work, with enough detail to know where each next action belongs.
