Pre-reqs do vary somewhat between med schools.
For example, some med schools don’t require ochem 2 if the student takes biochem. A few med schools require Calc 2 and other UL math classes; most don’t. Some med schools specifically require classes from the English dept in order to fulfill the writing skills requirement for med school.admission; others will accept any coursed designated as writing intensive by the individual college. Several med schools required additional UL biology coursework beyond Into Bio 1 & 2. (OSU require anatomy. Duke requires cellular biology or genetics)
A number of med schools no longer require specific admission coursework, but have competency-based admission standards that allow students to demonstrate the required competencies through a variety of means.
