Okay, I know this thread is kind of over but I just wanted to say that I am shocked by how aggressive people are being. This kid is acknowledging that he screwed up and that he wants to fix it. He is just looking for some advice; what is wrong with trying to fix your mistakes?
I’m going to be part of the Kenyon class of 2023 and obviously, that doesn’t make me qualified to give you advice, but I will anyway:
It’s a huge thing for someone to acknowledge that they messed up and actively try to fix their mistakes. You’re not going to find a specific answer on here, because there isn’t a specific cut off point. However, I’m sure you know that a D or an F definitely puts you in a danger zone. You can’t go into this striving to get a specific grade, you just have to work your butt off and do the best you can; fixating on a certain letter won’t do you any good. Without a doubt, the first step is to talk to your teachers and find out what you can do aside from the regular course work.
Wishing you the best of luck - I hope to see you next year!
