<p>I keep hearing different answers and I'm getting really paranoid so could anyone tell me at what point can NU revoke your admission? Is it just C's D's and F's or do they look at how much your grades have changed? If I had straight A's all through high school and will get 4 B's this semester, is there any chance of me getting kicked out?</p>
<p>I know most people say B's don't matter but since I had straight A's and someone said they look at how much your grades change, should I be worried?</p>
