Admission Revoked?

<p>Does this really happen? How bad can my grades get before I get my acceptance revoked?</p>

<p>I am so worried about this right now. In Anatomy, I pulled up my grade every quarter including last, in English I pulled up my grade, in History I got a better score than last 2 quarters, but Trig...oh my god...First quarter I was getting a 100 but I didn't make up a missed test (forgot all about it) that I could have aced, and got a 70. Second quarter I brought it up to a 91. 3rd quarter, 93. But this last quarter, I really messed up on 2 quizes that I could have aced but it didn't happen. I made some really stupid mistakes and got a 57 on one and a 67 on the other. Anyway, I am pretty sure I will be getting either a D or god forbid an F this quarter.</p>

<p>Will this **** everything up? Do they contact you before revoking admission so you can at least explain things? I worked hard this quarter to bring up my Bs to As (some low Bs to high Bs) and I don't want this D/F to **** it all up. :(</p>
