You have to retake a class you failed in Canterlot High in summer school. Not that you didn't try or are stupid...you just...have difficulties studying and concentrating...however another issue you have is anger, and it's really come back to you when you find yourself beaten up by someone you picked a fight with. Now you're in the nurses office and trying to not pass out from pain...well at least nurse Redheart's so good to her student/patients.
