Up until this year, I have loved math and been good at it. My average for pre-calc last year was 97. I was able to get through the first half of this year with Bs, but now that we're doing integration with substitution, natural log, and trig functions, I wanna rip my hair out! I have a 70!

I honestly am kinda interested in the topic, but I don't have the time or motivation to learn it all.
Is anybody else struggling with Calc?
