You need to ask them. What we think doesn’t matter. Our school only allows retakes for Fs and only offers courses required for graduation and only offers them at the regular level so we don’t have college-bound students trying to improve their GPA by re-taking classes and I would guess that’s a pretty common policy, so I’m sure there are many other students out there who like you had some kind of personal or health issue that brought down their grades… Your GC can explain the situation in your letters so I wouldn’t worry too much about it one way or another, as long as you are in a better situation now and able to perform better.
