5.5 Scale GPA Calculator (5.50 Scale)
The 5.5 Scale GPA Calculator calculates weighted grade point averages for school districts utilizing a 3-tier weighting structure where Advanced Placement (AP), International Baccalaureate Higher Level (IB HL), or University Dual Enrollment courses award a +1.50 grade point bonus (Grade A = 5.50).

What Is the 5.5 Scale GPA Calculator (5.50 Scale)?
Essential definitions, letter-to-point mappings, and systemic academic context.
A 5.5 GPA scale is an advanced secondary education weighted grading framework that distinguishes between standard courses (4.0 max), Honors/Pre-AP courses (4.75 or 5.0 max), and college-level AP / IB Higher Level (HL) / Dual Enrollment courses (5.5 max with +1.5 weighting).
Regular courses award A=4.0; Honors courses award A=4.75 (or 5.0); AP/IB HL courses award A=5.50, B=4.50, C=3.50, D=2.50, and F=0.00.
Allows high schools to recognize college-level courses with greater mathematical weight than standard honors classes.

| Course Title | Letter Grade | Grade Points | Credit Hours | Quality Points |
|---|---|---|---|---|
| AP Calculus BC | A | 5.50 | 1 | 5.50 |
| AP Physics C: Mechanics | A | 5.50 | 1 | 5.50 |
| AP Computer Science A | A | 5.50 | 1 | 5.50 |
| Honors British Literature | A | 4.75 | 1 | 4.75 |
| Total Summary | 4 Credits | 21.25 Total Quality Points | ||
Step-by-Step Arithmetic:
- Step 1: Assign weighted points: AP Calc (5.50), AP Physics (5.50), AP CS (5.50), Honors Lit (4.75).
- Step 2: Multiply by 1.0 credit each: 5.50 + 5.50 + 5.50 + 4.75 = 21.25 Total Quality Points.
- Step 3: Divide by 4.0 Total Credits: 21.25 รท 4 = 5.3125.
- Step 4: Round to two decimal places: Final Weighted GPA = 5.31 / 5.50.
Weighted vs. Unweighted 5.5 Scale GPA Calculator (5.50 Scale)
Understanding course rigor adjustments, quality point bonuses, and transcript ceilings.
Unweighted 4.0 Standard
Without 3-tier weighting, the student has a straight 4.00 unweighted GPA.
Weighted 5.5 Advantage
The +1.50 AP bonus boosts the GPA to 5.31 (+1.31 above unweighted).
Credit Weighting on 5.5 Systems
Full-year AP lab courses carry double the weight of single-semester electives.
Weighted GPA is 7.50 รท 1.5 = 5.00 vs 4.75 simple average.

What is a 5.5 GPA scale?
A 5.5 GPA scale is a 3-tier weighted system where standard courses cap at 4.0, Honors courses cap at 4.75 (or 5.0), and AP / IB Higher Level courses cap at 5.50 (+1.50 weighting bonus).
How does a 5.5 GPA convert to a 4.0 scale?
