From the developer:
TeacherTool is a software utility that calculates the percentage and letter grade for tests, quizzes, or assignments. Upon entering a total score, the user enters either the number missed or number correct...the software will keep track of the number of A's, B's, C's, D's, and F's for the particular score as well as the class average. The user can choose to use the default grading scale or use their own.
