Ticket into my lab midterm :D

My lab time is usually from 9:30-12:30. However, the lab midterm is only an hour long, and we have to draw for tickets to see who comes at a later or earlier time. I got the later time (only 2 exam times per regular lab time) and my friend was instantly trying to trade with me (do I want to do the exam from 9:30-10:30? Not when I've got a class right before!).
