Courses for each semester come out in a booklet about 2 months before the beginning of the next semester. Class lists are also online if you know the name of the class and the class number. I'm not sure how to get around campus. Campus maps are in booklets at the Information Center. Also, you can get a bus schedule for the free SIU bus which goes all over campus and around town.
Many students walk, ride bikes, or park on campus.
Finding parking on any college campus is not easy, so check with other students before deciding to buy a Parking Sticker for your car. I think my English is good, but sometimes I do not understand someone who uses slang words or has an accent. You may just have to ask the person to explain what they mean, even if it feels embarrassing. If you do not feel comfortable asking the person what they mean, try to remember the word so you can ask friends later what the word means.
