All hypos should be written down. Some legal concepts, which take many words to explain, can be summed up in one word or phrase, for example, proximate cause or constructive eviction. When you hear one of these words or phrases used in class, write it down. These are magic words. You will get points on the exam if you know what these terms mean and can use them correctly.
Some professors begin or end the class with a summary of what happened last time.
This review will be an invaluable guide to how the Prof. wants a problem to be analyzed. Legal analysis is very orderly. Elements must not only be analyzed separately, but in a certain order. Make sure you know both the elements, and the order of analysis. Finally, the professor may also discuss different topics that seem unrelated to the case.
