What strategy are you using to "level up" with Khan? I'm curious because I'd like to do this as well but am not sure where to focus.

  Well, I just started with the Algebra II classes cause that's about where my math skills were at... I've had calc I and discrete math in college, plus a lot of formal logic training but that was a long time ago. I was doing the "mission" style where they give you almost random tasks, and then you do mastery challenges... I feel like that got me a good into understanding a bunch of trig, matrix, and vector things that I hadn't understood before. However, I just wrapped up my precalc with that and decided to move on because the last couple of topics were boring and they kept sending me mastery challenges of tedious stuff. So for the calc I switched from the missions style to the lesson style because it feels more directed and "completist", and I've just been doing lectures and exercises. In the last couple of days I've gotten about half way through the material on limits. When I finish the calc, then I will do the statistics, and the multivariate calculus. At that point, I think that I will be ready to move into college level classes online for linear and whatever else I think I want. My larger interests are on one hand machine learning and AI and on the other hand, audio electronics for music... my math skills have held me back in electronics and I feel like if I am going to find anything useful in applying
