I think the "Grade Planner" should have a course-grade boundary option. Not all courses necessarily give an A for 90% and above, some have their own boundaries. Although, such courses would be a minority, having the feature will be beneficial. There should be button, which can allow you to set these unique/new grade boundaries via a letter grade - percentage chart. For example, 95% - A, 90% - A- and so on. The user must be able to just add these values to the table. So ideally, there must be a slider button which if not turned has the default grade boundaries. But if turned on, the user can input these values. This could be considered as a long term addition to the website.
