Are you an Ontario student whos sick and tired of that mark update, then when you finally get it, its not what you expected? Well, this app is for you! Levels is an app that is specifically designed for Ontario students who have trouble calculating their final grade for certain categories such as Knowledge, Thinking, Application, and Communication.
