How people in the world judge you.
They're usually based on a scale of 1-100, with 100 being the best, or f - A+, with A+ being he best.
You get these grades in school, such as on a test or as an average for the class. if you get a bad
grade on a test, it hurts your average grade for that class and
lowers your
self-esteem. Your parents will also get angry at you and won't stop talking about until your average in that class goes up to an "acceptable" grade by their standards.
Example:
Person 1: I have a horrible
grade in
ILA class.
Person 2: What do you have in that class?
Person 1: a D+
Person 2: WTF!!?! YOU ARE GOING TO END UP AS SOME HOMELESS GUY BEGGING FOR CASH FROM THE SMART KIDS IN YOUR
GRADE! YOU BETTER GET THOSE GRADES UP!
