A magic word that causes students to get pressured by parents and causes teachers to get stressed out, becoming deranged psycotics.

Warining: it may cause suicide... It may also cause student's future to never be fulfilled and the occasional assumption that they are future high school dropouts. It may also cause most deaths in the Asian population:
A- Average
B- Below Average
C-Crap
D-Death/Disowned
F- Fucked
Example 1:
Person 1: How'd she die?

Either a letter, check mark, or numerical percentage, awarded to students to serve as an arbitrary means of evaluating one’s academic performance regarding various scholarly subjects and thus assessing one’s comparative worth against his/her pupils. Grades originated out of social necessity through individuals who were too stupid to recognize whether or not someone had any intellectual value without a universal standard to measure by.
The most stupid example of grades is the minus/plus system, which penalizes the achievers and rewards the slackers.

An evaluative calculation based on alphabetical sequence that is used to make one a slave to the system and puppet to labor. Holds no correlation with intelligence, wisdom, or knowledge.
Student A: I got A's for all my grades.
Student B: Wonderful, now go properly learn.

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.
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!
