Common questions
Is a 3.5 GPA good?
On the standard 4.0 scale, 3.5 sits between an A- and B+ average — comfortably above the typical US college average (around 3.1) and competitive for most graduate programs, internships and scholarships, though the most selective programs skew 3.7+. Trend matters too: an upward trajectory reads better than a flat one.
Is a 90 an A or an A-?
In plus/minus systems, 90–92 is typically an A- and 93+ is an A, which affects GPA (3.7 vs 4.0). In straight-letter systems, everything from 90 up is simply an A. This calculator shows the plus/minus convention because it's the most common — your syllabus decides which applies to you.
