Question 1

How are weighted grades calculated?

Accepted Answer

Weighted grades are calculated by multiplying each assignment's percentage score (earned/total) by its weight, summing the results, and dividing by the total weight. For example, if you scored 90% on a midterm worth 30% and 80% on homework worth 20%, your weighted grade is (90*30 + 80*20) / (30+20) = 86%.

Question 2

What is the difference between weighted and unweighted grades?

Accepted Answer

Unweighted grades treat all assignments equally regardless of their importance. Weighted grades assign different percentages to different categories (e.g., exams 40%, homework 30%, participation 30%), so more important work has a bigger impact on your final grade.

Question 3

What do letter grades correspond to in percentages?

Accepted Answer

Common letter grade scales are: A = 90-100%, B = 80-89%, C = 70-79%, D = 60-69%, F = below 60%. Some schools use plus/minus modifiers (e.g., A- = 90-92%, A = 93-96%, A+ = 97-100%), though specific cutoffs vary by institution.

Question 4

How can I improve my overall grade?

Accepted Answer

Focus on assignments with the highest weight in your grading scheme, as they have the most impact. Use this calculator to determine what scores you need on remaining assignments to reach your target grade. Also consider extra credit opportunities if available.

Question 5

What happens if my total weights do not add up to 100%?

Accepted Answer

If your weights total less than 100%, your grade is calculated based on the weights provided, which may reflect only part of the course. If weights exceed 100%, it could indicate extra credit. This calculator will warn you if the total weight differs from 100%.
