I failed my calc final in high school. (67%. 70% was the lowest D grade.) I didn't learn much of anything, except that the Greek symbol "sigma" was used a lot. I really don't know how I managed that 67%.
College: Calc I. First test: 69.5%. There was one guy there who managed 100% on every test. Well, almost. Sometimes he got higher, since the teacher started adding bonus questions. I devised new laws of mathematics, wherein numbers randomly change into others. x^2 becomes x. 14-7 = 4. 2*2=1. Things like that. These are also known, more commonly, as "stupid mistakes."
That, and I just had trouble keeping straight the various derivative and integral tables. I still have trouble keeping it straight which way sine and cosine go - derivative of sine is cosine. Derivative of cosine.......negative sine. And I sometimes mix up integration and differentiation.
Calc I - got a B. Same with Calc II. Then a C in Differential Equations. If there was no partial credit on the tests, I would still be in Calc I, hoping to manage a C.

Psh, infinity? That's easy. Memorizing integration tables with many equations that are quite similar? Not so easy.
