It's really easy to use, the lessons are short and easy to understand, the teacher is good at explaining the concepts. The main problems is that once you've watched a lesson 90% of the time it doesn't check that you finished it, and there's no way to manually check that you finished it, so it can be easy to loose track. The other problem is that the app struggles to even work, it wont work out of wifi, and it sometimes won't run the tests even on wifi. Otherwise it would be 5 stars

Hi, Hunter! Could you please try a few basic troubleshooting steps? Oftentimes, uninstalling and reinstalling the app and/or closing any background apps on your device solves any issues you could be running into. If the issue persists, please submit a support request in our Help Center: http://khan.co/KA-support. Hope this helps!

Excellent easy to follow and understand. I've been out of school for 30 years and needed to relearn/refresh my memory to help my middle school son and this worked wonders. I was an expert in literally 20 minutes after 5 videos. Took a 4 question quiz after and got a perfect score.

the content is so good, but the content navigation is so confusing, too many categories, too many different ways to study the same content. there should be a simplified way of ordering the content, I remember back in 2013 when the math content was so straight forward, now it is such a convoluted, humongous, overwhelming, neverending path that it becomes hard to bare, and I find myself discouraged to even attempt to resume my learning
