CSE Calc 2 is beating my ass

We have a test on Thursday, and despite doing all the homework, I don't know how to do any of the problems on the practice exam. I put in hours a week trying to understand it, and I just keep forgetting it all. 😭

Plus they expect me to have all these formulas and trig identities memorized, and integration has so many things that I can try and so many ways to go wrong, idk how I am supposed to do it under time pressure of a test.

I'm gonna have to skip all my classes tomorrow just to attend tutoring.

Idk if this is normal for a CSE class or not. Like, I'm taking physics 1 for scientists and engineers and that shit is ez and fun compared to this nightmare.
