High school and college students in the U.S. have a "GPA". This stands for "Grade Point Average". It's a number between 0 and 4.0 which represents the average of all the student's grades. It works like this:

• An "A" in a class is worth 4 points.
• A "B" is worth 3 points, a "C" is worth 2, and so on.
• You take the average of all the grades to get a "GPA".
• You talk about the GPA as "__ point __". For example, "three point five".

A 3.0 GPA or higher is considered OK. Lower than that isn't good to put on an application or resumé.

If a student's grades are low, they may try to "bring their GPA up". This means to get better grades in their classes, so that the average rises.
