Implementation

``javascript function calculateWeightedGrade(grades) { // grades = [{score: 95, weight: 20}, ...] const totalWeight = grades.reduce((sum, g) => sum + g.weight, 0); const weightedSum = grades.reduce((sum, g) => sum + (g.score * g.weight / 100), 0); return (weightedSum / totalWeight) * 100; }``

What Grade Do I Need?

Calculate the minimum final exam score needed: Required = (Target - Current × (1 - FinalWeight)) / FinalWeight

Frequently Asked Questions

How do weighted grades work?

Each assignment category has a weight (e.g., tests 40%, homework 30%, final 30%). Your score in each category is multiplied by its weight, then summed. A 90% on a 40% weight test contributes 36 points to your final grade.

What grade do I need on my final?

Use: (Target Grade - Current Grade × (1 - Final Weight)) / Final Weight. If you have 85%, want 90%, and final is 30%: (90 - 85 × 0.70) / 0.30 = 101.7% needed (impossible—aim lower!).

How do I calculate GPA from grades?

Convert letter grades to points (A=4, B=3, C=2, D=1, F=0), multiply each by credit hours, sum them, and divide by total credit hours. Some schools use +/- modifiers (A- = 3.7, B+ = 3.3).
