AP Economics and AP Calc... How to pass!!

<p>I'm a senior and I'm applying to college. I finished my applications, and I feel so good about everything. Until I look at the classes I'm taking now. Seriously though, I don't know what's going on. I have NEVER gotten below a 90 in any class ever. Mind you, I've taken six APs already so it's not like APs are new to me. And yet, I can't pass AP economics AND AP Calc! First quarter I did fine in both of them, not my usual 90 which was kind of scary, but I got an 89 in economics an an 88 in calculus so I let them slide. Now in economics my teacher gave us a pop quiz, which I failed!! It was a small quiz so you get one question wrong, you're screwed. I got a 50 on that quiz. WHAT! Then the unit test came and I'm like ok I got this! I got a 70. WHAT! So now I have a 62 in economics. I talked to my teacher and she told me that as long as I do good on the two other unit tests and the midterm I'll be fine but I don't know how to do good on those! Then there's Calc. I took a quiz in Calc. Bombed it. 45%. How can I even do so bad?! Then I thought I understood the unit, took the unit test, and got a 62%. I have a 60% in Calc. I don't know what to do! I thought I wasn't stupid, but apparently I am! And colleges are going to see this! What am I supposed to do, I need to make it into college!!</p>
