Bad Grades and chances of being rescinded

<p>I am a senior and I got accepted to IU for in-state. </p>

<p>My first semester grades were: My second semester grades were:
AP Calculus: F AP Calculus: F
AP Biology: F AP Biology: D
H Economics: A- Government: A-
H Band: A H Band: A
AP Music Theory: A- AP Music Theory: A
H Spanish 4: C- H Spanish 4: F
AP English: C+ AP English: C-</p>

<p>They never said anything about my first semester grades, and my second semester grades are only slightly worse. I got a 1980 on SAT and 29 on ACT. I'm pretty worried, and it is my own fault. How likely is it that my application will be affected?</p>

<p>Lol I am in a somewhat situation as you. I have straight C+'s and one D+. Hopefully we’ll be fine unless you got into direct admit…</p>
