The exercises aren't that in-depth. They only really go up to introductory differentiation. It's clear that the focus of the assessment exercises is a secondary/high school target, and there's a lot of video content pitched at an undergrad level which is completely unassessed.
Hello, I was wondering: how many of you are doing khanacademy?
Right now, I am about 2 weeks away from completing khanacademy altogether. 334 out of 380 concepts are completed, assuming that the KA team don't add any new content during the time period.
Are you guys brushing up your math on KA, and if so what's your progress?
