This is very important, because it tells students what classes have to be completed prior to registration for this class. A co-requisite is also indicated, which means that there is a class that must be taken during the same semester as BIO 106. This is the section number, which is the unique identifying number assigned to each class. Be sure, when filling out your registration form, that you have correctly copied the section number of the class you want to take. Always double check class times and locations to make sure that they do not conflict with your personal schedule.
Room numbers do occasionally change as well.
An updated schedule of room assignments is mailed to your home one week before classes begin. Knowing the name of the class instructor can be helpful. Other students who have taken the class can offer information and advice about particular professors. TBA is not a hardworking ubiquitous professor, but an abbreviation for To Be Announced. This simply means that the class instructor was not known when the schedule was printed.
