About GPA Calculator
This is a credit-weighted average on the standard US 4.0 scale, so a four-credit A pulls harder than a two-credit A. Enter each course as name, grade, credits — one per line. Institutions vary: some use a 4.3 scale that lets an A+ exceed 4.0, and some weight honors or AP courses upward.

Questions
Why does my calculated GPA differ from my transcript?
Usually the scale. Check whether your institution counts A+ as 4.0 or 4.3, whether it uses plus/minus grades at all, and whether it weights certain courses. Repeated and pass/fail courses are also often excluded.
How do I work out what I need next semester?
Add your existing courses as one line with the total credits and your current GPA as the grade equivalent, then add hypothetical future courses and watch the result move.
Is the arithmetic exact?
It uses double-precision floating point — about 15 significant figures, far more than the inputs justify. Displayed rounding is cosmetic; the underlying numbers are not rounded between steps, so chained results do not drift.
