I was so excited to find this app. I've always wanted to learn about a lot of different subjects and now I can/am! Some of the ancient history time line is a little off, it's based around the Christianity/religious timeline. (Which I thought was super lame.) I was super impressed with how much education app has to offer. It's not all just boring, having to read 50 pages in order to finish one section of a section. You go by your own pace of course. Highly recommend.

Khan academy/the people/videos/tests are all incredible. Everyones voices are very pleasant,the videos and explanations are quick(much appreciated),as well as very informative and really drives the point home explaining in it several different ways, so it's easily understood, and memorable. The little test along the way really help make sure you understand too. I was ecstatic when I finally completely understood how to solve an algebraic equation! That's never happened before! So thank you!

The app does not work on chromebook most of the time, which is of course a problem. However, I have just logged into my acount online, and I must say, Khan Academy is amazing! It has content on about everything and many practice problems for math. The only negative besides it not working on Chromebooks is that the videos can get a little long and not totally on point in my opion.
