How much time should I plan to devote each week to an online class?
This depends on the class and how familiar you are with the subject. Generally you can plan to spend around 3 hours/week per credit. So, you would typically want to set aside around 9 hours a week for a 3 credit course. Additionally, you should plan to log into Moodle at least three different days per week to make sure you are staying on track with course assignments and deadlines.
