@umichstudenthelp - As I’ve said several times in this forum already, admission officials are likely to grant a lot more “wiggle room” for low grades this semester due to the pandemic and to all the changes and confusion it’s spawned. BUT … one red flag for me here is that you said that you weren’t able to turn in late work because of it. I’m not clear on why this is so. Can’t you submit work electronically at any time?
If you’d gotten just the two C’s, I’d tell you not to worry due to this spring’s extra flexibility, but two C’s AND a D could be a problem, especially if your explanation about the late work sounds suspicious to the admission folks. So please post again and explain in more detail why you couldn’t submit your late work. (Perhaps your inability to turn in your work is related to the reason that you missed school in the first place and might account for it?)
It’s still likely that your acceptance will stand, even in spite of these plummeting grades, but I can’t say that it will with as much conviction as I’ve had in other recent instances when students have asked about the impact of a couple of C’s.
