Seriously...first of all CHILL OUT!
Second of all, practice, practice, and practice some more. Your goal is to eventually reach the point where you read through a question and a major issue jumps out at you. It helps to compare "hypos" as you call them in your old practice test. Think about what each question is emphasizing. Ask yourself how the questions are different and where the professor is pointing you towards. For example, in Contracts, if you read a hypo which gives you all of these facts about the interaction between two people in coming to an agreement, you want to talk about the different ways a contract can be formed. This is different from a hypo which gives you facts about two people with an ongoing contract and one of them has failed to fulfill their end of the bargain. In this case you would probably want to discuss the remedies for breach of contract. Learn do distinguish the different types of hypos!
