Ratings and Reviews
Khan Academy is an education app for everyone—whether you’re a parent helping your first grader with geometry or a postgrad looking for a deep dive into microfinance. If there’s a topic you want to learn about—no matter how basic or advanced—chances are Khan Academy has a video lesson for it.
This app is amazing, but
It is a little bit hard to study biology, chemistry, etc. because Russian is my native language (I’m not bad at English but sometimes I get a little bit confused). It would’ve been so so great if you would’ve added Russian to it, but I’m already so obsessed with this app! Thank you for what you’re doing and continue to develop!
Developer Response ,
Please know that we continue to add new content to offer a better content library on Khan Academy. I encourage you to share your request in our discussion forums (http://khan.co/KA-content-requests), where users can add their thoughts to yours and vote on your suggestions.
This !free! app is easily beating several paid courses and applications I have used in the past in both video materials’ quality (deep explanation and nice humor) and user interface.
I am personally studying Algebra courses, so I can definitely recommend them, I suspect that other courses are great as well.
