Reflection to Self-grading tests

I really like the idea of using self-grading tests in the classroom. Its really neat that some of them will create a chart showing how students answered each questions. This will definitely become useful because it gives you instant results on what you may need to re-teach. A large group of students may have gotten the same question wrong, which means you may not have made the information for that question you were teaching clear to the students.This would make the self-grading tests very beneficial.
