This outline of the entire Contracts I course as taught by Professor Gregory E. Maggs of George Washington University Law School may help smooth out some of the rough edges you've encountered in your own study of this course.  Remember that the approach your professor may have to some of the topics may vary considerably from Professors Maggs' approach ... and you may have covered more or less in your class.

These outlines from LexisNexis provide an overview of the essential topics of seven subjects and may be helpful to prepare for class, to organize your notes, and for helping to design your personal course summaries!  Here are the subjects covered: Constitutional Law, Contracts, Criminal Law, Criminal Procedure, Evidence, Property, Torts, and Trusts & Estates.
