The mark of your class' dumbest Asian girl is the Q-point.
Any marks above this is known as a Q+
Any marks below this is known as a Q-.

Getting Q- usually results in an automatic fail on that exam/assignment/quiz/course.

Mathematically, the PDF of the Q-point is Rayleigh distributed (With Marks on the X-axis, from 0% to 100%)
Student A:"Hey man, what did you get on your exam?"
checks Asian girl's marks.
Student B:"Not good man... Not good... Q-point..."

Professor: "See 'ya next year!"
