So, this might be a bit of a long post, TLDR at the bottom. I posted a couple weeks ago about my Mechanics class that I'm taking, and about how much it sucks. It will be the easiest A that I've ever gotten, in that, our grade is 80% homework and 20% lab grade coupled with the fact that my professor said verbatim on the first day of class, "I know all the answers are out there on Chegg, if you want to cheat, then cheat." No tests, no final. Seems awesome, but since I actually want to learn this stuff and that my prof's lectures suck balls, makes it quite difficult. He just reads the text off of the PowerPoint slides made by the book company, so it's just like reading the book. My textbook is also like hieroglyphics to me at this point. I can understand the conceptual bits, and even follow the derivation of the formulas, but then the homework is crazy. It's Pearson MyLab, and when I Chegg questions to follow, sometimes I'll be like, "Ahh, damn. Yeah, I should have used that," and then others I think, "How in the actual fuck should I have known to do that?"

I've been watching Michel Van Biezen videos and taking notes as well as reading my book, but the way that Michel teaches is very different from my book, and so a lot of the problems are very different. Especially multi-part questions and questions that want answers in terms of variables. This process is taking me so long. I spend like 4 hours reading a textbook, just to get to the homework and realize I have no idea what to do. Then, I watch a bunch of videos, kind of know what to do and Chegg my way through the homework. I think about the topics a lot, and after getting through the homework I do understand it better, but not that well. I'm taking Calc 2 and Computer Science 2: C , and I'm killing it in those classes. Got A's on my first two Calc 2 tests, and have like a 98% in CPS2. But, I just can't understand physics without it being taught to me.

I feel like I'm wasting too much time on this physics class now, and that it's taking too much time away from my other two classes. This is compounded by the fact that my next Calc 2 test is on series. The only other prof who teaches physics at my school is verrrrrrrrry hard to pass. Notorious for lots of tests and quizzes. I have to take physics 2 next semester, and I'm probably going to take it with the same guy, just so that I know I'll pass. It sucks, but I'm being honest here. So, my question to you is, going forward (and as an EE student) what topics from mechanics will reappear and should I have down for future classes? It would be awesome to have it all down, but it doesn't look like that's going to happen. Is there anything in my process that I can change to make my learning process more efficient? I'm 100% teaching myself at this point.

TLDR: What are the most important topics from Mechanics to have for E&M/being an EE major?

Also, the book we're using is: Principles and Practice of Physics, by Eric Mazur. If that helps.
