Excellent content and assessments, daughter enjoys it and better than many of the paid for programs. Thoroughly recommend it.

You guys are really great! I recommended to a niece and she was able to pass her biology course university level!

My favourite service for studying new things. Currently I'm studying world history and storytelling, all the materials and exersizes are very useful, colorful design of the site makes studying more interesting and less boring!

Fantastic resource for all! I'm so very impressed with the extensive content available to everyone, for free, via Khan Academy. What a gift! I am especially grateful for their new partnership with the College Board to give all kids access to personalized and free SAT prep. Our son spent about 15 hours using only this program to prepare for the SAT and got an awesome score on his very first effort! (1520, 730v/790m) Thank you, Khan Academy!!!

Really great math help site. My son used Khan Academy and GreeneMath.com to ace the ACT!!!

Free website to study for college student. I am a Med Student and i love it!

I have found this website very much useful to learn fundamentals. I have learn mathematical fundamentals from this website. It is really helpful for the kids and school children and it's free source to educate yourself.

It is slightly inflexible when deciding what to learn. For instance in civilized countries learning by heart the transformations of ounces and pounds and miles are completely irrelevant, but other than that it is a great learning tool.
