Start here: No BS guide to Linear Algebra https://a.co/d/6em7tXE . There’s also a No BS guide to Math/Physics which goes through calculus and geometry. This is freshman level content. I read this on the couch next to my wife act age 37 for about 20-30 minutes a night, a few times per week and got through it in six months. You will need to work some of the exercises, i used a lap desk and clipboard which I store next to my spot on the couch.
