Actually, you can drill all subjects in a week by flipping vertically!
I have to admit, Im not often impressed by what CC puts out. The prices are usually more than what the product is worth and their priority consistently seems to be copyright protection over quality.
However, this app has exceeded my expectations. It is exactly what you can get through CC3, but in our case CC3 took forever to load and our kids quickly lost interest.
