An excellent piece of software that I, as a college student, wouldn not want to live without. It is very similar to DueYesterday (so much so that it seems certain that they are based on the same code), but superior to it in several ways. It's not perfect--for one, there's no OS X conduit for the optional subscription online portion--but it does its job well. If you want a free student planner, try DueYesterday. If you're willing to shell out a few bucks, 4.0Student is the best I've found.
