Frequently Asked Questions

How do weighted grades work?

Weighted grades assign different importance to different assignments. For example, if homework is 20% and the final exam is 40%, the final exam has twice the impact on your grade.

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

The calculator will still work, but results may not be accurate. Make sure all assignment weights in your class add up to 100% for the most precise calculation.

Can I calculate what I need on my final exam?

Yes! Use the Final Grade Calculator tab. Enter your current grade, target grade, and final exam weight to see what score you need.

How do I convert between different grading systems?

Use the Grade Converter tab to convert between percentage, letter grades, GPA scales, and points. This is helpful for comparing grades across different schools or systems.

What's the difference between grading scales?

Different schools use different standards. Standard scale: A=93-100, Strict: A=94-100, Lenient: A=90-100. Choose the scale that matches your school's policy.

How accurate are these calculations?

The calculations are mathematically accurate based on the data you provide. However, actual grades may vary due to rounding policies, extra credit, or other factors your teacher considers.

Can I add assignments with zero scores?

Yes, you can enter 0 for assignments you haven't completed yet. The calculator will include them in the weighted average, which helps you see your current standing.

What if I get over 100% on an assignment?

You can enter scores over 100% for extra credit assignments. The calculator will handle this correctly and may boost your overall grade above 100%.

How do I handle curved grades?

Enter your actual scores first, then apply any curve to your final calculated grade. Some teachers curve individual assignments, others curve the final grade.
