Math course recommendations?

Web: https://www.reddit.com/r/datascience/comments/sam6js/math_course_recommendations/

I've been doing a lot of code studying on my own, and I feel fairly competent in Python and SQL, but back when I was a student I hated math. I think I need some stats/calc to bolster my skills. Does anyone have any recommendations for what more specific mathematic areas to look into for data science, or maybe even specific courses online?
