I used to be a mess of a student before iStudiez
I CANNOT STRESS ENOUGH how important this app is. Ive been using for a year now (two semesters) and my GPA went up a good amount and I believe its because of iStudiez. I tend to forget about assignments all the time and it tracks your grades and course averages. It makes organizing your classes and grades more efficient. Yeah it costs a pretty penny or two (especially for the Mac version) but its completely worth it.
