<p>My college counselor always said this:</p>
<p>Colleges will accept one C anywhere on your transcript as you not getting the material or maybe having a rough time with the teacher. Once you have two or more, though, they’re going to start questioning you.</p>
<p>
Getting a D is pushing it after acceptance in my opinion. You have to think about the kind of grades you showed Pitt you were capable of when you applied. If you were an A/B student, you need to maintain that A/B standing. Pitt is going to be confused why you’re suddenly doing poorly, and ask for an explanation of what happened to the stellar student they accepted.</p>

<p>Is this a 79% without the weighting? I can’t imagine it would. Pitt is also considering how tough your classes are, and AP Calc is no joke. Besides, wouldn’t a 79% be a B-? That’s acceptable for the most part, and with a curve, it would go up. And since your overall GPA is not being poorly affected, I don’t think they will mind.</p>
<p>A random aside: At my high school, on AP Calc was offered (we were an AP school). My sister’s high school was an IB school (so IB Calc). The year I took AP Calc, my sister was doing IB Calc…turns out we were using the same textbook! It was great because if I ever forgot mine, I’d just run to her room and use hers. So…even though it’s IB and AP, it’s Calc. You can’t really change the material taught, lol.</p>
