You may, however, have questions that you need to have answered between classes. All composition faculty keep regular office hours. Instructors generally indicate their office hours on their syllabi and they also post them on their office doors. You should feel free to stop by your instructor's office during designated office hours. If you have a schedule conflict during your instructor's posted hours, then you will need to make an appointment for another time.
Most faculty are willing to make such appointments with reasonable advance notice.
Check your syllabus for your instructor's phone number. Do not call your instructor at home unless he or she gives you express permission to do so. These faculty members will probably list their e-mail address on their syllabi. You can do this by signing up for one in SGC B102 . You can also sign up in the same place for an e-mail training session or an internet training session.
