<p>OP:</p>
<p>It isn’t that important. If knowing things was important for medical school admissions, the requirements would go beyond introductory classes in a few subjects. </p>
<p>The reason why course rigor is not too important is because being a doctor isn’t an academic job, it is a vocation. Medical school and residency is job training. Few people drop out of medical school because they can’t handle it intellectually.</p>
<p>Folks. Humans are writing these rec’s, whether they be individual or committee. Committee letters are done in various ways. Some are a packet of individual rec’s. Some are a compilation with excerpts, some are well…I dunno. But different. 
Humans will bring every bias they have, intentionally or un-intentionally, to the process. </p>
<p>If you skate…they will (likely) re-cip-ro-cate. </p>
<p>Don’t be that guy or gal. It’s not a rep you want. </p>
<p>Don’t take hard classes because they are hard (or look hard). Take them because you will learn something you want to learn. Don’t stay away from the great prof because they grade hard but fairly and consistently. Stay away from any prof that grades randomly and without regard to any identifiable form of course mastery.</p>
