The Princeton Review categorizes a 3.25 GPA, or grade point average, as equivalent to successfully completing 87 to 88 percent of required coursework or a B letter grade. A GPA is a four-point scale used to measure academic achievement.
Many high schools and colleges use a four-point scale for grading. A grade point average of 3.5 or above is equivalent to an A letter grade. GPAs of 2.5 to 3.4 represent B letter grades, while averages in the range of 1.5 to 2.4 correspond to C level or average work. GPAs between 0.5 and 1.4 are D level or almost failing, and anything under a 0.5 is failing.
