<p>C's aren't actually an average grade. The average GPA at most high schools is well above a 2.0.
Back to the original question, I really doubt one C will lead to a scholarship being rescinded. You still picked up 5 A's for the semester after all, it's not like you slacked.</p>
<p>Pick it up as much as you can. One C won't probably do it, but err on the side of caution; I'm from California and most of the states schools (UC system like Cal, UCLSA, UC David) here will recind your acceptance if you get a C your senior year!</p>
<p>If your scholarship is merit money because you had a certain GPA and you no longer have that certain GPA yes, NYU can pul back their money if you no longer meet the criteria (remember that the school will get a copy of your final transcript) so work on pulling up those grades for june.</p>
