[D] Math resources for self learning

Okay so I'm an undergrad engineering student studying AI & Data Science. Unfortunately the university I go to sucks (one of my worst decisions was to join this uni). My math basics and foundations are very weak (like calculus, stats and linear algebra) but I'm very interested in the field of ML. When I say weak they are REALLYY weak. Is there any roadmap that I can follow to strengthen my maths concepts before diving into ML? Can you guys …
