Summer Classes

So I know you can take lower level classes over the summer but does this also apply to upper level classes. I’m thinking of taking my two engineering classes over the summer so I can focus on finishing my prereqs for med school next semester

I’m a bit confused. Medical schools don’t want you to take your pre-reqs at schools other than the one you are attending (for example, by taking Bio at community college over the summer). But there is no reason why you can’t take classes - especially those that are not pre-reqs, at your own college over the summer.

Am I missing your question here?
