Grades are not what causes stress. Grades are just what monitor success. You shouldn't blame grades for stress that is caused from the classes. If you are stressed out, try talking to your teacher or changing classes.

I do not think we should do away with grades. Grades are what show how well a student is doing in school. Without grades or a similar system, parents, colleges, and anyone else who wants to know how well a student is doing in classes would be unable to. Students would be able to slack more knowing that their progress would not be monitored
