Is an A+ worth more than an A at Purdue?+
No. At Purdue, an A+ and an A are both worth 4.0 grade points. This differs from schools like ASU, where A+ carries 4.33.
How is Purdue GPA calculated?+
Divide your total grade points by your total credit hours. Each course contributes grade points × credits. Pass/Not-Pass (P/NP) courses do not count toward your GPA.
Do Pass/Not-Pass courses affect my Purdue GPA?+

Purdue uses 0.3-point steps (A- = 3.7, B+ = 3.3), while UF uses one-third-point steps (A- = 3.67, B+ = 3.33). The differences are small per course but add up across a full transcript.
What GPA scale does Purdue use for grad school applications?+
Purdue's official transcript uses the 4.0 scale above. Graduate programs and credential services may recalculate using their own method, so confirm with the school you're applying to.
