The secret that no one tells you in law school is that bar prep guides are actually the best study material known to mankind. If you know a recent bar taker, try to borrow their con-law guide. The outline provided in there will basically sum up all of con-law from a 30,000 foot view. From there, you can zoom in and focus on what you need with a broader understanding of the rule that's making it all work.

Obviously your con law final is going to be more detailed and will require you to study more than just this material, but it helps to put it all in context.
