How the Purdue Grading System Works
Purdue University uses a standard 4.0 grading scale with plus/minus quality points.
Standard 4.0 Cap
Like the vast majority of American universities, Purdue caps grades at a 4.0. This means that even if you earn an A+ in a course, it will carry the exact same mathematical weight (4.0 grade points) as a standard A. Focus your efforts on maintaining A's across the board rather than killing yourself for the A+.
Admissions Requirements & Target GPA
If you are a high school student applying to Purdue, you should be aware that their admissions committee looks at both your weighted and unweighted GPA. While the exact incoming freshman average changes yearly, competitive applicants typically aim for the highest possible percentiles.
We recommend cross-referencing your calculated high school GPA with the official Purdue Admissions guidelines to see how your academic profile compares to their most recently admitted class profile.
