I love that I can create multi-select questions, make answers worth partial credit or bonus credit, and fix errors to the key with an easy tap of the buttons. Even after tests are scanned, changes are instantly made to all my students' quizzes or tests!
Better still, I can easily fix mis-scans and student errors in ZipGrade without a rescan. If I question a student during follow-up 1-on-1, and they orally answer correctly, I can change their scanned answer in seconds!
And since I'm always trying to improve as a teacher, item analysis shows me what I need to reteach (when students answered all over the place) and what questions were worded ambiguously or on which students were unanimously mistaken. Next year, I can teach those concepts better or change the question to be more clear!
My wife and I both use it for small quizzes and large tests, and we recommend ZipGrade to every teacher out there!
