Students who have taken eCore courses before say that their biggest piece of advice is to log in to the course just about every day. Often, this means that you are just spending a brief time checking announcements, emails, responding to discussion postings and making sure you have submitted anything that is due.
Doing this will make you feel more connected to the course and not so overwhelmed because you're doing a little each day rather than playing catch-up. Of course, you do need to set aside some larger chunks of time a couple or more times each week to do some serious reading and completion of assignments and quizzes.
eCore courses also carry a required log in deadline during which time students must complete orientation assignments within the first few days of class.
