Make a habit of checking what’s due and when at least twice a week. In the past, if I only checked the course once a week, I was almost guaranteed to miss something.
If an assignment description doesn’t seem to make sense, make sure to email the instructor immediately, as sometimes it’s difficult to express a certain degree of nuance in written descriptions.
Make sure to at least look over assignments before automatically saying, “I’ll do it later.” Something that you thought would take 15 minutes can end up taking a lot longer, putting stress on you and possibly causing you to miss an assignment.
