I started doing math exercises with Khan Academy to compare it to Brilliant. The khan academy exercises are more straight to the point: just do the damn math.

Brilliant turns every exercise into a meta-learning word problem. It might be “better” for learning concepts but it felt like it was going way too slowly (fun and edutaining, but slow).

I just want to plow through some early maths problem sets right now to get my brain spooled back up and find out what I don’t remember anymore.
