By recommend, I mean content you actually find to be high quality, well done, and easy to absorb and follow. By relearn, I mean I have forgotten everything I ever learned in high school.
In the past I wanted to do the same because I have the same problem as you but I never actually gotten around to executing the learning part... The one resource that picked my attention the most is https://youtu.be/didXE0HkSC8 ("Learn Mathematics from START to FINISH (2nd Edition) "). It's a 37 minute video with dozens of book recommendations and how you should proceed with the order of those books.
