Frequently Asked Questions

Is 90 an A or A-?
In this calculator's conversion bands, 90-92 maps to an A- (3.7 GPA), while 93+ maps to an A (4.0 GPA). Some schools use different cutoffs.
Can I get a GPA higher than 4.0?
On an unweighted 4.0 scale, 4.0 is the maximum. Weighted scales (for AP/IB classes) can go higher, but this calculator only estimates an unweighted conversion.
Why do schools convert differently?
Grading policies are set by individual institutions. Some schools use a straight scale (90-100 = 4.0), while others use the +/- system used here.
