To apply for medical school, you should start the application process about 1 to 2 years before your intended start date. The application cycle begins in the spring of the year prior to when you plan to start medical school. For example, if you intend to start medical school in the fall of 2026, you should begin applying in the spring of 2025. Submitting your application early, ideally by early June, is crucial due to rolling admissions, which favor earlier applicants.
