I'm starting grad school today and would like to find a good student organizer app. there are a couple in the app store but I would like some real input as to which is the best. some examples are Grade Pro, iStudiez, iHomework, etc... I would like something that can deal with weighted grading scales and also has the ability to add semesters so I can keep a running GPA calc. syncing isn't a top priority, but calendar sync is preferrable. anyone have some experience with any of these apps or have a better suggestion?
