Math Academy and a SQLite course pulled me out of despair as well. I grew up thinking I was relatively smart and being able to learn on my own, but only randomly and sporadically. After not learning much the past few years and feeling very stupid, I decided to look for some paid courses to take on Hacker News.

The SQLite course was in a very different video format and took roughly 20 hours, but I learned a lot and immediately used that knowledge in two software projects that would've seemed insurmountable to me.

As for MA, it's taken a lot longer and has been difficult. I'm now at 6000XP and halfway through Fundamentals II. I have a lot of thoughts, but I (kind of) plan to (probably not) write a review after having completed Foundations I-III, since I haven't talked to anyone else who's done so so far.
