Grade points × GPA credits = quality points
For the example A = 4, B = 3, C = 2 scale, A/3 + B/4 + C/2 gives 12 + 12 + 4 = 28 quality points. Divide by 9 credits to get 3.1111…, displayed as 3.11 with rounding.
Blank, excluded, and failing are different
Blank rows are incomplete and omitted, with a visible count. Invalid completed rows block the estimate. An excluded grade contributes no quality points and no GPA credits. A included zero-point grade still contributes its GPA credits.
Precision stays in the calculation
The course GPA engine accepts up to two decimal places for credits and two or three for policy grade points (including NYU CAS). It accumulates scaled integers, divides only at the end, and applies the policy’s final rounding, truncation, or semester or cumulative cap. The planning tools use standard floating-point arithmetic and are estimates.
The selected policy matters
Generic grade scales are examples, not school policies. Institution profiles identify their source and version. Their first release supports finalized undergraduate coursework only and blocks a calculation when you flag an unsupported case. It cannot detect all omitted or misclassified coursework for you.

No admissions probabilities, scholarship decisions, graduation audits, universal percentage conversions, or aggregate weighted-to-unweighted conversions are produced. Consult your institution for an official academic record.
