<p>The medical schools that use credits to describe requirements generally are looking at the how credits are structured at their own undergraduate college. </p>
<p>Typically—</p>
<p>4 credits = 1 semester (16 weeks) of a class that meets for a minimum of 3 lecture hours + 1 hour of recitation each week. (64 hours)</p>
<p>A quarter (12 weeks) class that meets 3 lecture hours + 1 recitation hours would not be considered equivalent to 4 credits because it doesn’t meet for same total number of hours. (64 hours vs. 48 hours)</p>
<p>When D1 transferred from college that ran on quarters to one that ran on semesters, each of her quarter classes were pro-rated as worth 3 credits at school where 1 semester course = 4 credits.</p>
<p>As I said above, it’s safer to ignore credit equivalencies since this varies so much from college to college.</p>
