If I failed to learn, and the average grade dropped the first thing I would do is set up to review the idea and the result will come later if I don't tell my mother. And if my mother came to know later to regret so much?
If I failed classes and GPA dropped the first thing I would do is stay calm and think about the consequences that will follow later that if I did not tell my parents. If parents will later regret it.
If I fail in the class and grade point average dropped the first thing I want to do is stay calm and think of the result will come later that if I didn't tell mom and Dad If you later will be very sad
