I taught myself everything up to and including Linear Algebra and Differential Equations, and am currently teaching myself Multilinear Algebra and tensor analysis.
Also, what is your age, and how long did it take to teach yourself?
I'm 14 and I started self-teaching myself physics and mathematics at age 10, stopped at 11 for reasons I decline to provide, and started back up again at 13. It has taken me ~1 year to be self-taught this far.
