Michael,
I'm farily new to AIU (4 Sessions completed), but I've developed a pretty good habit of grading essay/research papers within the 48 hour mark. Most students will submit their work on Sunday night (deadline is 11:59pm). I start grading on Monday and will alternate from top to bottom on the roster to make sure each student does not get graded the same time each week. With larger class sizes, I usually complete half the class on Monday and finish the other half on Tuesday (within the 48 hour mark). For those exceptional students, who submit prior to Sunday, I have about a 24 hour turnaround. Hope this helps!
