How this is calculated
Divide the points earned by the points possible and multiply by 100: 24 ÷ 30 × 100 = 80%. On the common 10-point-band scale that lands in the B- range — you'd have needed 27/30 to reach the A band.
Common questions
Do withdrawals (W) hurt my GPA?
A W doesn't enter GPA math at all — that's usually the point of withdrawing. It does appear on the transcript, and a pattern of many Ws can raise questions in competitive admissions. One or two strategic withdrawals to protect a GPA is common and rarely damaging.
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.
