【實用工具app】PerCentz|最夯免費app-綠色工廠好玩App

PerCentz quickly calculates a percentage score based on the total number of problems and the number right or wrong. It's for teachers who have a lot of worksheets, tests, or quizzes to grade and can't instantly calculate any percentage in their head, which, I think, includes almost all of us! It's designed to be as easy and fast to use as possible.
