# High School GPA Calculator

High school GPA is a cumulative grade point average used to indicate academic performance of high school students. It's a little complicated because there're different course systems in the world.

For each of your assessment, you must choose what kind of course you are in. This GPA calculator supports regular high school courses, Honors courses, AP(Advanced Placement) courses, IB(International Baccalaureate) courses.

High schools usually add 0.5 points to a students grade for taking an Honors class. For AP and IB clasess, extra 1 points will be added because they are basically college curriculums.

# How to calculate high school GPA in letters

## Formula

gn: grade of the nth assessment

cn: credit of the nth assessment

wn: extra weight of course, 0.5 for Honor, 1.0 for AP/IB/College

Grade = ( g1×c1+ g2×c2+ g3×c3+...+ gn×cn)÷ (c1+c2+c3+...+cn)

Weighted Grade = ( (g1+w1)×c1+ (g2+w2)×c2+ (g3+w3)×c3+...+ (gn+wn)×cn)÷ (c1+c2+c3+...+cn)

## Example

 Grade Credit Course B(3.00) 2 Regular B+(3.33) 2 Honor B+(3.33) 2 College A-(3.67) 2 Regular

Grade = (3×2 +3.33×2+3.33×2+3.67×2) ÷ (2+2+2+2) = 3.33

Weighted Grade = (3×2 +(3.33+0.5)×2+(3.33+1)×2+3.67×2) ÷ (2+2+2+2) = 3.71

## Formula

gn: grade of the nth assessment

cn: credit of the nth assessment

wn: extra weight of course, 0.5 for Honor, 1.0 for AP/IB/College

Grade = ( g1×c1+ g2×c2+ g3×c3+...+ gn×cn)÷ (c1+c2+c3+...+cn)

Weighted Grade = ( (g1+w1)×c1+ (g2+w2)×c2+ (g3+w3)×c3+...+ (gn+wn)×cn)÷ (c1+c2+c3+...+cn)

## Example

 Grade Credit Course 86%(3.00) 2 Regular 87%(3.33) 2 Honor 88%(3.33) 2 College 90%(3.67) 2 Regular

Grade = (3×2 +3.33×2+3.33×2+3.67×2) ÷ (2+2+2+2) = 3.33

Weighted Grade = (3×2 +(3.33+0.5)×2+(3.33+1)×2+3.67×2) ÷ (2+2+2+2) = 3.71
