Taking Back admission offers?!!?

<p>I was just wondering, I got accepted to Columbia yesterday and I was wondering what it takes for them to take back admission offers, considering GPA. Throughout high school, I've had all A's with the exception of two B's. I've had a really busy semester (working 40 hours a week) and I have four A's, a B, and unfortunately a C. Do you think I should be worried? I don't know if I can raise that C by the end of the semester. Thanks.</p>

<p>you'll be fine relax, just don't get a C average.</p>

<p>Unless you really screw up, at worst they'll put you on academic probation to start, which means you'll have to have an average over 3.0 (flat B) your first semester. You'll be fine, as the only person I know who had to start on probation failed a class their senior year.</p>

<p>Thanks guys, I can't tell you how much I've been worrying about that.</p>
