Weighted caps are local lore
Plenty of districts cap weighted GPAs at 5.0, but a few IB schools quietly allow 6.0+ for extended essays and HL courses.

How this calculator works
Unweighted GPA uses your base scale (4.0 or 4.33). Weighted GPA adds per-course bonuses (Honors +0.5, AP/IB +1.0) and caps each course by the Max Weighted Cap (default 5.0). GPA = Σ(grade points × credits) ÷ Σ(credits).

5 Fun Facts about GPAs
A+ isn’t universal
Some colleges ignore A+ entirely (treating it as 4.0), while others use 4.33—so the same transcript can shift a class rank overnight.
Scale surprises
Credit hours are leverage
A single 4-credit course can outweigh three 1-credit electives. Loading heavier credits with strong grades moves a cumulative GPA much faster.
GPA physics
Repeat rules vary wildly
Some schools replace the old grade; others average both attempts. A “retake boost” at one campus can barely budge GPA at another.
Retake reality
Pass/Fail still matters
Pass grades usually add credits without points, so they can dilute a stellar GPA if you stack them—helpful for balance, sneaky for math.
