Super Grader Lite is an application that assists teachers when grading students assignments, tests or exams.
Simply enter the total possible score for the paper/exam/test then use the wheels to calculate the grade. For example if the student missed 4 questions from a possible total of 20, enter 20 in the Total Q's box at the top of the screen then scroll down to 4 on the missed wheel. This will calculate the students score, percentage and letter Grade.
The default grade ranges used are A 90 - 100, B 80 - 89, C 70 - 79, D 60 - 69 and F 0 - 59
