I don't use it systematically anymore, but it's my first port of call when I don't understand something in school or want to hear something explained differently. It works pretty well when I use it in this way, although he often goes through things more slowly than would be ideal for revision purposes.
So, you just use the videos and not the exercise?
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?
