text: "Re-Learning" or "Learning again" is very important! Say you forgot it and need to go over it again, you can do that by asking the teacher and another student to help you go over it, or form a study group. And if you already know, don't fear, you can just help yourself out by learning the details, you did not last time. And if you learn it again, you should be able to do it more constistnantly, so you get the right answer more often. So don't try to say "I have learned it once, I know what to do" and sat " maybe i missed something, let me check!"
