All instructors have office hours and are required to be in their offices for a certain amount of time every week to help students and provide extra support. This information is available on the course outline you receive in the first week of class. They are expecting to see students and welcome questions about their course so come prepared with specific questions to take advantage of this valuable time.
When emailing faculty and staff include your full name, your student ID number, and the class you are in. Please follow a formal email format and be as polite as possible. Allow 3-5 days for a response and remember that your instructors have many students in their classes.
