Set a regular time to work on course assignments, spending 2 hours per week of study time for every credit taken in addition to normal "class hours" required for a course.
Avoid distractions and interruptions. Dedicate a time to work on the course and stick to it.
Be able to use the technology properly. Find out in advance of taking the course what computer skills you are expected to have.
Find out where the Help sections are located for computer related problems, for online resources, and especially where updates to assignments will be posted.
