I identify so hard with your comment! I’m proficient with a handful of programming languages, very comfortable with most Sys admin tasks on Unix-like OSes, and I’m almost always able to reverse engineer someone else’s similar solution to meet my needs. However, I’ve had any formal computer science education. Now, in my early 30s, I’ve found a successful career in a non-tech field but find it unfulfilling. I still love to program and I’d love to make a change, but my lack of a math and comp sci foundation gnaws at me.

I’ve tried to relearn Calc a handful times, but find myself frustrated when I have to go look up basic trig identities, and order of operations stuff just to get through practice problems. I’d love to relearn math from scratch if anyone has any recommendations.
