AP Score Estimation Formula
Composite Score = (MC_Correct × MC_Weight) + (FRQ_Score × FRQ_Weight)
AP Score = lookup(Composite Score, subject_cutoff_table)
Multiple-choice and free-response raw scores are weighted and combined into a composite score, then mapped to the 1–5 AP scale using official College Board cutoff tables updated annually.
Square Root Grade Curve
Curved Score = √(Raw Score) × 10
This formula redistributes raw scores by taking the square root and scaling by 10, commonly used to shift class averages without altering rank order. Assumes raw scores are on a 0–100 scale.
GPA Calculation (4.0 Scale)
GPA = Σ(Grade_Points × Credit_Hours) ÷ Σ(Credit_Hours)
Each letter grade is assigned a point value (A=4.0, B=3.0, etc.), multiplied by credit hours, summed across all courses, and divided by total credit hours attempted.
