Do people take electives in their first semester even?
No, your first semester classes are set in advance for you (Contracts, Procedure, Criminal Law/Torts, and Lawyering). Spring semester you have three required courses (Legislation and the Regulatory State, Criminal Law/Torts, and Lawyering), but you can choose one of the following classes to take as your fourth: Constitutional Law, International Law, Corporations, Income Taxation, Property, or Survey of Intellectual Property.
Edit: if you haven't seen it yet, your class schedule is up on Albert! Check it out. Albert --> Student Center --> "Weekly Schdule". I'd suggest scrolling down and enabling course titles/professors to show, then skipping to the third week or so (the first two weeks listed aren't full weeks).
