Grade Calculator

Your overall grade is the weighted average of all assignments, tests, and exams. Multiply each score by its weight percentage, add them up, then divide by total weight. Example: Homework (20% weight, 85 score) = 17 points, Midterm (30% weight, 78 score) = 23.4 points, Final (50% weight, 82 score) = 41 points → Total = 81.4 out of 100.

Unweighted grades treat every assignment equally. Weighted grades give more importance to certain assignments (like exams count more than homework). Most courses use weighted grading because finals and midterms better measure overall understanding.

In most US schools, 60% (D-) is the minimum passing grade. In India, 33-40% is passing depending on the board. In many professional courses, 50% is the passing mark. Always check your course syllabus for exact requirements.

Use the formula: Needed = (Desired Overall - Current Weighted Score) ÷ Final Exam Weight. Example: Desired 85%, current weighted 80% with 70% of course done, final worth 30% → Needed = (85 - 80) ÷ 0.30 = 16.67% on final (very easy). If needed > 100%, you can't reach your goal.

In the 4.0 scale: 3.5-4.0 = Excellent, 3.0-3.4 = Good, 2.5-2.9 = Average, Below 2.5 = Needs improvement. For scholarships, aim for 3.5+. For graduate school, 3.0+ is often required.

Common conversion: 90-100% = 4.0, 80-89% = 3.0, 70-79% = 2.0, 60-69% = 1.0, Below 60% = 0.0. Some schools use plus/minus system (A- = 3.7, B+ = 3.3). Check your institution's specific conversion chart.
