You should know how laws are made. After all learning how to work with laws is why you are here in law school. The FDLP (Federal Depository Library Program) Academy has a series (3) of webinars that provide excellent information on the law-making capabilities of the legislature, courts, and administrative agencies. There is a research guide for each of the 3 topics at the University of Georgia Law Library website.
For the really fast and fun overview, there is the School House Rock: How a bill becomes a law.
