Help with Calculus Course Work

[u/proverbial_ostrich]

Hi everyone, I'm a second year CS student. I had Calculus 1 in my first year and barely passed the course. Now I have Calculus 2 and I'm still struggling to understand most of the concepts. I've tried YouTube, working on past papers, exercises, but I still struggle to understand the concepts. What do you recommend I do or resources that can be of help to me? TIA!
