Is a 3.1 GPA Good?
A 3.1 GPA on the unweighted 4.0 scale is roughly a B average — about 87% — and it sits right around the national college average — solid standing, and many opportunities list 3.0 as their cutoff.

Context that matters more than the number
GPA is read alongside course rigor and trajectory. A 3.1 earned in a demanding major with an upward trend reads better than the same number from an easy schedule that's sliding. Mathematically, raising a 3.1 takes time: one straight-A semester of 15 credits moves a 60-credit GPA by only 0.18 points — which is why starting the climb early beats a senior-year sprint.

How are letter grades calculated from percentages?
Most US schools map percentages to letters in 10-point bands: 90–100 is an A range, 80–89 a B range, 70–79 a C range, 60–69 a D range, and below 60 an F. Plus/minus splits each band roughly in thirds (e.g. 90–92 = A-, 93–96 = A, 97+ = A+). Individual schools and professors can and do vary the cutoffs.
