Frequently Asked Questions

How do I calculate weighted grades?

Weighted grades consider the importance of each assignment. Multiply each assignment's percentage by its weight, then divide the sum by the total weight. This gives more importance to major assignments like exams and projects.

What's the difference between GPA systems?

Different countries use different GPA scales. The US uses a 4.0 scale, while other countries may use different ranges. This calculator converts between systems to help you understand your performance across different grading standards.

How do I improve my grades?

Focus on assignments with higher weights first, as they have more impact on your final grade. Use this calculator to see how different scores would affect your overall grade, helping you prioritize your study time effectively.

What if my weights don't add up to 100%?

The calculator will still work, but your weighted average may not reflect the true course structure. Try to ensure your weights total 100% for the most accurate grade calculation. You can adjust weights to see how they affect your final grade.
