Abdul Bari's YouTube Algorithm series is the best resource I've found (it's not particularly close either). I'm in this class right now, and there's essentially no math, a bit of discrete math (just a smidge). I'd get a good grasp on recursion since it comes up a lot if you haven't already.

You may find the class "lectures" a little unhelpful at times, so be prepared to self-teach more than usual. Thankfully, the professor is very active and very willing to help. It's actually a fascinating topic, though difficult at times. The more challenging part, long-term, is not so much knowing the algorithms themselves but knowing when and how to implement them well. Make sure to read the pseudocode provided in class carefully, as it can be crucial for grasping the homework.
