It's helped me tremendously - just started university, and we had a teacher who just wasn't that good. Nice person, not enough teaching experience. Looked up Khanacademy, and a second explanation made it stick. I'll use it to repeat things later on. Started peeking into javascript too, as I've yet to write a single line of code in my life, it's a much appreciated source of information.
Did you do any of the exercise? How much if you do so.
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?
