I work them again as frequently as I need to to remember them. I don t want to learn someone else s mistakes. Mark I use a group to study for tests. I start the problems before I go to group. At least, I try to look them over.
Group is a good place to find back tests.
We usually have found different ones and we trade. I catch people before and after class and discuss problems with them. Maureen I do the problems before I go to group. If people in the group have different answers, we try to find out who is correct. I try to share what I know and also learn from other group members.
