Yes, there is homework in law school before the very first day. After August 1, you will be able to find the syllabi for your classes on the Semester Information page. The syllabi will list what books you need to purchase and what you need to read before the first day of class.
While some professors prefer a more modern, lecture-style approach, many still apply the Socratic Method, as demonstrated in this clip from The Paper Chase. While most professors aren't quite as derogatory as Professor Kingsfield from the film, if they use the Socratic Method they will ask you about the facts of the case, the final outcome or "holding" of the case, the reasoning behind that holding, and the reasoning behind any concurring or dissenting opinions. They may even ask you if you agree with the reasoning or what you would have done differently. The underlying logic behind the Socratic Method is that the purpose of law school is to train students to "think like lawyers," which often involves coming up with policy-based arguments.
It can take some students time to adjust to the Socratic Method, especially since it is rarely used in undergraduate courses. However, the most important aspect is that you have to read the assigned materials before class. Otherwise you may end up exactly like poor Mr. Hart.
The link below will walk you through how to print from your laptop or mobile device to the printers located in the law library on the 9th floor. The law school printers are AL910A, AL911A, and AL911B (since our building code for the Angelos Law building is AL and the printers are on the 9th floor).
If you do not have your laptop or mobile device, you can always log into the lab computers using your UB ID and print from there.
Also, note: students are allotted 350 pages of free printing each semester. If you exceed 350 pages, you can purchase additional pages at a rate of $5/100 pages). More information is at the link below.
Okay, so now you've got a basic idea of how the first day and the first few weeks are going to go. But what if you need more help studying? What if you can't remember about personal jurisdiction or the different types of mens rea?
