Too expensive, takes up to much space.

I was forced to download this app in order to complete mandatory summer homework for my chemistry II class. It costs too much, and I didnt have enough memory to download each video even after deleting every single app I owned. (Plus, the SAME videos are on YouTube if you know the name of the video. I recommend doing that instead.)
