If all of the grades for a class are a letter (say MS), an overall grade of a letter for that class should show. This way, especially during the Phase III grading policy during the 2020 pandemic, students can quickly see if there are any classes they need to look in more detail at the grades.
However, although I believe this app should be 4 stars, I have to put it at 5 because of all the nonsense spam reviews that are just lowering the rating for absolutely zero reason.
