Worried about CSE 260 [Discrete Math] as someone who really sucks at Calculus

I have CSE 260 (with Yiying Tong) on my schedule for next semester, but I’m a little worried because the only college math I’ve taken so far is Calc 1-3, and I barely scraped by Calc 3 this semester.

I know they’re pretty different, but I guess I wanted to know if anyone did terribly in Calc but found Discrete manageable.

I don’t technically have to take it as I am not a CS major, but I will be entering a CS-related field after undergrad. I’ve heard that it sets a good foundation for data structures & algorithms as well as other core computer science skills, which is important to me.
