It actually was out, you just need a piece of paper and write the expression on one side and the answer on the other.
Then put them in different folders or boxes depending on if you fail them or get them right, down a box or up a box.
Then do the lowest box every day, the next every 3 days, every week, etc.

It doesn't take a genius to come up with something like this. The japs do it with these little card holders for english.
