Customer Reviews

Such clear instruction!

I came to this app after having trouble understanding math concepts while studying for the ACT. Though I haven't checked out content in all subjects, the mathematics section is exactly what I was looking for. Not only are you shown how to solve a problem, but why it makes sense. While some don't feel it is necessary, this is an important part of learning for me. These videos are the reason I feel confident for the test. Best part is it's FREE! Thank you to the creators. The effort to share knowledge, and make it easily accessible is clear and appreciated. Only 2 things I could think of to make it better. An ACT section (there is an SAT section), and the way the app exits a video of it is paused. (If you exit the app or your screen goes black the video must be restarted.)

Concept is Wonderful, the App is shotty

The videos (so far) have all worked without a problem, but when it comes to seeing where you've left off or need to continue from isn't instantly marked off or highlighted. Transition from video to an question lesson should be transitional. Instead I have to go back to the menu and select where I have to go next. And only when you open and close the app is when you get to see where you might continue. I can't edit my profile, or even see the other tabs that are in my profile. And what exactly are the points for? What are they based off of? There are some cosmetic flaws that could be fixed, sooner rather than later. This new update didn't fix anything noticeable.

Khan Academy: Overall Very Nice!

I heard about Khan Academy through a television commercial and decided to try it out. I recently watched every video for college admissions and finances! It has truly been a giant help in that area. However, I wish the music section had more depth. I will be going to college for music education and was quite disappointed when I looked through the music category! Only three videos, and relatively simple (simple is NEVER bad when first starting music or to get a general idea). It could grow and branch into bigger planes of theory and history than what is listed. In my opinion music is heavily lacking, but other than that this app is great to brush up or learn new things! Truly a wonderful layout, colors, organization, resources, etc.
