Students must register during the official registration period at the times announced in the university calendar. They should plan their courses with their advisers prior to registration and follow the instructions in the students’ booklet and Registrar’s web page: Students must attend the section of the course for which they are registered. No instructor has the authority to permit a student to shift from one section of the course to another without following official drop/add procedures. Students are responsible for registering on time and for the correct courses. Students may not attend classes without being properly registered for them, and cannot receive credit for courses in which they are not registered and students may not register or add courses retroactively.
