Right now it seems pretty easy. I am only taking 3-6 credits a semester and the most work I have had to due for classes is writeups on readings, group projects, etc.
Biggest pain is the work you have to do to get in. Apply, write 3 essays, take the GMAT, get 3 professional references. Seemed to take more work to get in then I currently do in classses.
If you graduated from ISU and do the MSIS program there are several classes that are waived. I only have to take 27 credits (9 classes) to graduate. Of course there is the whole creative component/thesis thing I need to start, but haven't come up with a good idea yet.
