Grade Calculator

A weighted grade average is a method of calculating a final course grade that gives different assignments different levels of importance. Rather than treating every assignment equally, a weighted system assigns a percentage weight to each category of work — for example, homework 20%, quizzes 30%, and final exam 50%. This reflects the reality that not all academic work contributes equally to demonstrating mastery of a subject.

The weighted average formula multiplies each assignment's score by its weight, sums those products, and divides by the total weight. For example, if a student scores 90% on homework worth 20% and 80% on the final exam worth 80%, the weighted average is (90 × 0.20) + (80 × 0.80) = 82%, not the simple average of 85%.

Understanding how weighted grades work empowers students to make strategic decisions about where to focus their effort. Knowing that the final exam carries 40% of the grade helps a student prioritize exam preparation over lower-weight assignments near the end of a semester.

The Weighted Grade tab calculates your current course grade:

1. Enter the assignment name (e.g., "Midterm Exam").
2. Enter the raw score you received.
3. Enter the maximum possible points for that assignment.
4. Enter the weight of that assignment (e.g., enter 30 for a 30% weight).
5. Click "+ Add Assignment" to add more assignments or grade categories.
6. Click "Calculate Grade" to see your weighted average percentage and letter grade.

The Final Exam Calculator tab answers "what do I need on my final?":

1. Enter your current grade percentage before the final exam.
2. Enter the weight of the final exam as a percentage of the total grade.
3. Enter the desired final grade percentage you want to achieve.
4. Click "Calculate" to see the score you need on the final to reach your goal.
