Has this helped you?

It definitely kept me busy

Regardless of whether it did, the practice is better than no practice for developing an intuition.

Yes for physics

It helped me when I was 16. Pretty decent discussion of Newtonian physics, but not very useful for anything beyond that. Perhaps you can learn the basics of special relativity, but at that point you should really be learning it along side electrodynamics and Khan academy wont teach you that.

Yep, Taylor polynomials and Linear Algebra. I think Khan Academy is excellent as a refresher or for filling in some gaps.

Everything on Khan I've seen has been good. Was the reason I 1st discovered 2x video speed, and now slowly working to 4x video speed.

If nothing else, the mathematics knowledge map is worth the visit.

It's pretty okay for people with few studies and college entry level but for PhD level hardly helps at all

Needs specialization,a lot.

It's a good place to start whne you are in unfamiliar territory but you quickly outgrow it when you get down to the nitty gritty details. But yeah its a great beginner tool.

just checked it out. unfortunately the german part has only the math part, which is pretty basic. i might be a handy tool for kids in school.

Helped me a lot for mathematics.

Not so much for my other modules though, as I am an engineering student. But 10/10 would recommend for math.

Yeah the linear algebra stuff is amazing, saved my ass. Laplace transform content for differential equations was also solid.

>>8192571
awful.

disorganized.

Guy's handwriting is shit.

Was great for precalc but dropped it in calc, shit was too slow for my taste

Yeah, I used it to check out some finance stuff. Turns out Khan was a hedge fund analyst. So, he really knew his shit there.

Yeah, it's really good if you're returning to mathematics after a long break, he explains it from the ground-up. The exercises are neat too.

For science or higher-level mathematics though, I'd prefer textbooks. However, I'd refer to Khan Academy in case I didn't understand a certain concept from said textbook. Textbooks also have more difficult problems.
