I dropped 2 classes that I reported this semester (and am down to 3 classes) in mid March and received my acceptance letter in mid-April. I did not know that I was supposed to report it until today, how likely will my offer be withdrawn if I let them know now that my semester is pretty much over (the day I posted this is my last final for the semester)?
I face facing the same dilemma. I was not doing great in the class so I thought about withdrawing. Before I do so I emailed them about withdrawing, their response was it shouldn’t affect the admission status as long as I let them know once I do so. I guess they just need to have a heads up from before seeing it on the transcript as a surprise.
