Good but needs a little work
I have been using this for 17 classes of about 20-40 students. I tried Teacher Pal last year but had a lot of crashes and could not quite get the grades set up properly. With Gradebook, I was able to set up the grades/grade calculations set up the way I wanted. On the other hand, there are a number of peace of mind robbing bugs that show up from time to time such as duplicate fields for students or exempted grades showing up for no reason or a kind of scroll stickiness that sometimes wont permit scrolling to the bottom of a long list of students. Had one particularly disconcerting bug where I could not access 16 of my classes until resetting my iPad. Even so, the app usually runs smoothly but strongly suggest regular back ups of data. Agree with another review that called Gradebook/Graybook ugly but then TPal was much prettier but did not work as well for me.
