Honestly, I think it was probably more burn-out than anything. I'm not so sure it was purely seniorities, although that factored into a little. I did simply want to have fun knowing it was my last time in college. I handed in assignents late, procrastinated (while doing more social activities), and put in less work overall.
But when I said my last quarter was bad, I mean really bad. It doesn't reflect in my overall GPA so much, but if you actually look at my transcripts you'll see typical quarter grades of:
A
A-
A-
B+
Whereas my last quarter was essentially close to:
C
D
C
Incomplete
B-

Would an adcom ding me for something like that (GPA b/n 3.3-3.6, btw....sorry for not wanting to be too specific)?
