This calculator helps you estimate your AP World History: Modern exam score based on your performance in different sections. Enter the number of questions you answered correctly in each section, and the calculator will provide an estimated scaled score and AP score. The AP World History: Modern exam consists of two main sections: the multiple-choice section (MCQ) and the free-response section (FRQ). The MCQ section is worth 40% of the total score, and the FRQ section is worth 60%.

// — Approximate Scoring Rubric —
// These values are based on general AP scoring guidelines and may vary slightly year to year.
// The MCQ section contributes 40% to the raw score, and the FRQ section contributes 60%.
// The total number of possible raw score points is usually around 100-120 (MCQ: 60 points, FRQ: ~40-60 points total).
// Approximate raw score calculation:
// MCQ raw score is typically 1 point per question.
var mcqRawScore = mcqCorrect;
// FRQ raw score estimation:
// DBQ: Each point is roughly equivalent to 1.33 raw points (7 * 1.33 = ~9.33)
// SAQ: Each point is roughly equivalent to 3.33 raw points (3 * 3.33 = ~10)
// These are very rough estimates. A more precise conversion would require the official scoring distribution.
var dbqRawScoreEstimate = dbqCorrect * 1.33;
var saqRawScoreEstimate = saqCorrect * 3.33;
var frqTotalRawScoreEstimate = dbqRawScoreEstimate + saqRawScoreEstimate; // This is a simplification. The actual FRQ scoring is more complex.
// Combine raw scores (this is a simplified representation as weighting is applied later)
var totalRawScoreEstimate = mcqRawScore + frqTotalRawScoreEstimate;
// Approximate conversion to scaled score (out of 100) and AP score (1-5)
// These are general benchmarks and will differ slightly by exam year.
var estimatedScaledScore = 0;
var estimatedApScore = 0;
// Simplified conversion: This part is highly variable and depends on the College Board's specific conversion tables for that year.
// For demonstration purposes, we'll use a very rough linear approximation and then AP score bands.
// A more accurate calculator would use College Board's official conversion tables.
// Let's assume a total possible raw score of approximately 100 for this estimation (60 from MCQ, ~40 from FRQ).
// This is a MAJOR simplification. Actual FRQ scoring and total points vary.
// A more common approach in calculators is to directly map raw points to scaled scores and then to AP scores.
// Based on general AP scoring guides:
// ~30-40% of total raw points for a 3
// ~50-60% for a 4
// ~70%+ for a 5
// A better approach for estimation:
// First, convert MCQ raw score to scaled score:
var mcqScaled = (mcqCorrect / 60) * 40; // 40% of scaled score comes from MCQ
// Then, convert FRQ raw score to scaled score:
// This is the most complex part without the official conversion table.
// Let's assume an average point value for each FRQ component to contribute to the 60% of the scaled score.
// DBQ (worth 25% of scaled score): Max 7 points. Let's approximate 25% of scaled score is ~25 points. So 7 points ≈ 25 scaled points.
// SAQ (worth 15% of scaled score): Max 3 points. Let's approximate 15% of scaled score is ~15 points. So 3 points ≈ 15 scaled points.
// This is a highly speculative simplification.
// For a more robust estimation, we can use established conversion tables, which change annually.
// As a *very rough estimate* for demonstration:
var estimatedTotalScaledScore;
if (mcqCorrect >= 35 && dbqCorrect >= 5 && saqCorrect >= 2) {
estimatedTotalScaledScore = 75; // Likely 5
} else if (mcqCorrect >= 28 && dbqCorrect >= 4 && saqCorrect >= 1) {
estimatedTotalScaledScore = 60; // Likely 4
} else if (mcqCorrect >= 20 && dbqCorrect >= 3 && saqCorrect >= 1) {
estimatedTotalScaledScore = 45; // Likely 3
} else if (mcqCorrect >= 15 && dbqCorrect >= 2) {
estimatedTotalScaledScore = 30; // Likely 2
} else {
estimatedTotalScaledScore = 20; // Likely 1
}
// This is a placeholder mapping. Official College Board conversion tables are necessary for accuracy.
// Example mapping (very simplified and not official):
if (estimatedTotalScaledScore >= 80) { estimatedApScore = 5; }
else if (estimatedTotalScaledScore >= 65) { estimatedApScore = 4; }
else if (estimatedTotalScaledScore >= 50) { estimatedApScore = 3; }
else if (estimatedTotalScaledScore >= 35) { estimatedApScore = 2; }
else { estimatedApScore = 1; }
