Have you ever looked at a syllabus and interpreted it wrong and ended up doing an assignment on the wrong day? I seemed to be plagued by this lately. In one of my classes, the assignment listed is the one that is DUE that day. In my other class, the assignment listed is ASSIGNED that day and due the next class period. It can be very confusing sometimes.
I spent two hours last night working on an assignment that I thought was due today, but it turns out my professor was just going to assign today. At least I have a head start now ... except that I had to read the chapter so many times last night to be able to understand what was going on.
