Khan Academy is well known in the education world as being a fantastic resource for students to watch videos to learn more about topics covered in class. It's also great for non-students who are just thirsty for knowledge and want to study a subject on their own time. And for free. The Khan Academy iPad app is the best way to put learning in your own hands.

Khan Academy covers a massive number of topics, including K-12 math, science topics such as biology, chemistry, and physics, and even the humanities with playlists on finance and history.

Each video can be streamed to your iPad or downloaded for offline viewing. If you wish, you can even download all the videos in a topic at once so that you don't have to click each one individually.

Most, but not all, videos include subtitles with each video. This is extremely helpful for those times that you can't understand what the instructor was saying, or if you don't know how to spell some term that the instructor said but didn't write down. These subtitles are shown underneath the video and can be scrolled through.

If you log into Khan Academy, you can keep track of your progress and earn achievements for watching videos and completing topics.

As of now, there are not any practice exercises available in the Khan Academy app, but they promise to bring them soon.

I've always been a fan of Khan Academy and recommend it to all my students as a fabulous resource. The instructors are very qualified for the subjects they are teaching and do a great job at explaining and making the topics interesting to learn about.
