How this service works
GPA on the 4.0 scale from letter grades and credits, with optional honors (+0.5) and AP/IB (+1.0) weighting.
Output
Returns the computed GPA on the 4.0 scale (to two decimal places), total quality points, total credits, per-course grade points and quality points, an unweighted GPA for comparison when weighted mode is used, a plain-language summary, a verdict, any disclaimers, and flags for degraded results or courses that could not be evaluated.
Example use cases
Semester GPA check with AP courses
“I got A-, B+, and A in my three AP classes this semester, all worth 4 credits each. Can you calculate my weighted GPA using AP weighting?”
College application GPA calculation
“I need my unweighted GPA for a college application — here are my grades: A in Bio (4 credits), B in History (3 credits), A- in English (3 credits), B+ in Math (4 credits), and C in PE (1 credit).”
Honors vs regular class GPA comparison
“Can you calculate my GPA both weighted and unweighted? I have: A in Honors Chemistry (4 credits), B+ in Honors Spanish (3 credits), A- in regular Art (2 credits), B in regular Health (1 credit).”
