Why credits matter
A 4-credit B at 3.0 contributes 12 quality points. A 1-credit A at 4.0 contributes 4. Together: (12 + 4) ÷ (4 + 1) = 3.20. An unweighted average of 3.0 and 4.0 would be 3.50 and would ignore the different course sizes.
A sample 4.0 table
The editable default table uses A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, and F = 0. Some schools use different plus/minus values or omit them. Enter your own point values in the GPA calculator.
Percentages and pass/fail
A percentage is not a GPA value. First apply your actual course cutoff to obtain a letter grade, then use the matching point value. Pass/fail can award credit without adding quality points at some schools; this first version excludes P and NP from GPA arithmetic. Check official policy.
Institutional rules that differ
Repeated courses, grade replacement, transfer work, withdrawals, incompletes, special extra credit, and program-specific policies vary. GradeScenario does not reproduce a registrar’s official calculation. See cumulative planning for a transparent estimate based on the credits you enter.
