'An underachiever doesn't know the fatigue of a high achiever, the high-achiever doesn’t understand the hardwork of an underachiever' speaks to differing struggles students experience based on their academic standing. This captures empathy gap or lack thereof regarding respective effort put into academics by top students vs those who struggle.
