Withdrawing from a class my last semester

[mis-dreavus]

I'm assuming this is the best place to post this question, but I honestly have no idea. Anyway, I've been accepted to two schools and I'm awaiting on a third. This semester I decided to take a history class as an elective. It's ended up being much harder than I thought it would be. I feel like I'm drowning every time I'm in class. After getting a 95 on an essay a couple weeks ago, I just failed my midterm. I actually felt pretty confident coming out, but I think the professor is also a much harder grader than I thought he would be. I'm not sure if I can salvage my grade at this point, as the midterm is 25% of my grade. Would the schools I've been accepted to think badly of me for withdrawing? I feel like I should also mention that I've never withdrawn from a class before and withdrawing from this one would push me down to a part-time student.
