Ratings and reviews

The app loads and works for me, I guess my 4 year old phone is the correct device and with the correct settings because everyone else says that the app doesn't work for them! It's very basic, it doesn't tell you if you were wrong or right, you select a chapter from the book and you're presented with a problem from that chapter and you can select a green check mark, a question mark or a red X, it just shows you the problem and that's it. You have to decide if you understand or not.

The app is not working. I restarted my phone and uninstalled/reinstalled the app with no success. When I tried to email the developer with the address given on the Play Store, it was returned as undeliverable.

Does not work. Opens to a yellow screen with a blue rectangle. Click the rectangle and a blank yellow screen is pulled up. I just loaded this on my tablet and it works. So far, so good.

What's new

High School Grammar and Composition are now included in the app.
