Is a 3.7 GPA an A or B?
A 3.7 GPA is usually an A-, not a B. It sits in the A range on most 4.0 plus/minus scales.
3.7 on the letter scale
A common scale is A = 4.0, A- = 3.7, B+ = 3.3, and B = 3.0. That places 3.7 clearly above B+ and B.
If your school does not use plus/minus grades, 3.7 may simply be described as an A-range average.
Why it matters
A 3.7 is strong because it shows mostly A-level work. It can still vary in meaning depending on whether the GPA is weighted or unweighted.
