How to use: Calculate grade averages from test scores with optional weighting for different assignment types. For simple average: Enter Scores comma-separated (e.g., 85, 90, 78, 92, 88). For weighted average: Also enter Weights as percentages that total 100% (e.g., 20, 25, 15, 25, 15 for different exam weights). Results show: Simple Average (unweighted mean), Weighted Average (if weights provided), and Letter Grade using standard scale (A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F below 60%). Essential for students tracking academic progress, teachers calculating final grades, and parents monitoring performance.

How to use: Calculate cumulative Grade Point Average from college or university courses. Enter Letter Grades comma-separated (A+, A, A-, B+, B, B-, C+, C, C-, D+, D, D-, F), and corresponding Credit Hours for each course (typically 1-4 credits). Results show: GPA on 4.0 scale, Total Credits earned, and Quality Points (credit hours × grade points). Standard scale: A/A+ = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Most colleges require 2.0 GPA minimum to graduate. Dean's List typically requires 3.5+. Essential for academic standing, scholarship eligibility, graduate school applications, and honors programs.
