Why use a weighted grade calculator?
Different assignments carry different importance. A final exam worth 40% of your grade should impact your average more than a quiz worth 5%. Weighted averages reflect this reality so you can accurately predict your final grade and focus your study time where it matters most.
How to improve your grade average
Identify your lowest-performing subjects and focus extra study time there. Use the weights field to see which assignments have the biggest impact on your overall average — a small improvement on a high-weight item moves the needle more than a big improvement on a low-weight one.
