The app quizzes don't work and I freaking brought this app
Bachod app... Never try to install it..
Its all great
Purchased but have NO ACCESS?! I purchased this AND the chemistry app in may and June of 2011, and now it tells me that I have to purchase the app again....what's the deal?!
Nothing special Must purchase after 1st mini-lesson. They describe it as fun, but they didn't design in anything fun. Stock with Kahn.
App now has videos and require in-app purchases.
