Rags to riches does help me prepare for and exam. I think its a good studying method. If they had it for all the subject areas pre-test studying would be a lot easier. You can study your notes all you want but if there is no interactivity in the studying, it is forgotten quickly.It is also a good way to study because it doesn't waste a whole bunch of paper like the math unit reviews. I wish i had this at my old schools. I wish we had a tech program like this at our old schools.
