There's no single answer — but there are common benchmarks worth knowing, depending on what the GPA is being used for.
These ranges are useful rules of thumb, but what actually counts as "good" depends a lot on:
Your school's academic catalog or registrar's office will list the exact GPA thresholds for academic standing, probation, honors, and graduation requirements — these are the numbers that actually apply to you, more than any general benchmark.
The Best GPA Calculator's "Academic progress scale" shows an example of how required minimum GPAs often scale with total hours attempted — but always confirm the real thresholds with your own institution.
