How to use it

Enter each course's grade, credits and level; honors adds 0.5 and AP, IB and college courses add 1. Enter each course's grade and credits; add your GPA so far for a cumulative GPA.

Grades can be letters (A+ to F, P or NP for pass/no pass) or percentages (0 to 100). Show the working gives the formula with your numbers.

Key facts

weighted points = letter points + 0.5 (honors) or + 1 (AP, IB, college)

Grade scales

Letters are worth 4 points for A, 3 for B, 2 for C, 1 for D and 0 for F. Plus and minus move a grade by 0.3 on the one-decimal scale (A− = 3.7) or by a third on the thirds scale (A− = 3.67); pick the one your school uses.

Pass/no-pass courses are left out of the GPA, as most schools do; their credits are listed separately.

Weighted and unweighted

An unweighted GPA tops out at 4.0 (4.3 with A+); a weighted one can go above because harder courses earn extra points. Colleges often recalculate GPAs their own way.

Questions

Why is my weighted GPA above 4?

Honors and AP grades carry extra points, so straight A's in them average more than 4.

Does an F get the bonus?

No; a failed course is 0 points whatever its level.

Formulas

weighted points = letter points + 0.5 (honors) or + 1 (AP, IB, college)

Limitations

  • Letter-grade points follow the common US 4.0 scale; schools differ, so check your own school's table.
  • Percentage bands for letters are the common 97/93/90 … 60 cut-offs.
  • Weighted GPAs add 0.5 for honors and 1 for AP, IB and college courses; some schools use other bonuses.
  • At most 50 rows.
