Here is a 28-page outline summary of the black-letter law of Contracts.

I highly recommend Understanding Contracts by Jeffrey T. Ferriell. Like the other books in the Understanding series, this volume provides a clear and concise explanation of the law. I referred to it regularly in studying for the bar exam and in creating these diagrams, and as usual, I learned much more from the Understanding book than I did from my casebook.
Seriously, if Contracts is not crystal clear to you, and you have not read this book, click on the image to take advantage of Amazon’s Look Inside feature and start reading.
