Depending on the course, you may have Office Hours or Review Sessions.
If you have any questions or would like to talk to your instructor, you can login in/call in anytime. These office hours are optional and are usually open for one hour. For example: PV 101’s Office Hours are on Tuesdays and Thursdays from 12p.m to 1p.m.
These are not recorded and are meant as an additional resource for students if they need it.
These are live web meetings are that are recorded, and then posted on your course website (mreacourses.org) so you can listen afterwards. Webinar recordings (links) remain active until the last day of the course.
Webinars are essentially live “office hours” where you can call or login, ask questions, and review concepts, assignments, and quizzes with your instructor and other course participants. These are usually once a week for about one hour.
