Depending on the course/section and/or instructor, you may get a communication a few days before or the day of class. Check your OCC email regularly and often. The instructor email should be listed in the details of the course/section you chose. Log in to MyOCC, select "Student" and go to "My Class Schedule". You should be able to click on the course and see the instructor’s name/email.
You may email your instructor to ask questions. However, he/she may not respond until the day of or just prior to classes starting. Check your email often so you don’t miss an important message. If no instructor is listed, contact the Department or call (248) 341-2000 to be directed.
