1. What is Weighted Grade?

A weighted grade is a calculation that takes into account the varying degrees of importance of different components in a course. It gives more weight to some assignments or exams than others when calculating the final grade.

2. How Does the Calculator Work?

The calculator uses the weighted grade formula:

Where:

• Grade — Individual assignment/exam score (percentage)
• Weight — Relative importance of that assignment (decimal)
• ∑ — Sum of all components

Explanation: Each grade is multiplied by its weight, these products are summed, then divided by the sum of all weights.

3. Importance of Weighted Grades

Details: Weighted grades accurately reflect course structure where some components (like final exams) count more than others (like quizzes). They help students understand their true standing in a course.

4. Using the Calculator

Tips: Enter grades as percentages (e.g., 85, 90.5) separated by commas. Enter corresponding weights as decimals (e.g., 0.3 for 30%) also separated by commas. The number of grades and weights must match.

5. Frequently Asked Questions (FAQ)

Q1: What if weights don't add up to 1 (100%)?
A: The calculator automatically normalizes weights by dividing by their sum, so results will be correct regardless.

Q2: Can I use this for non-percentage grades?
A: Yes, as long as all grades use the same scale (e.g., all out of 20 points).

Q3: How do I calculate my final course grade?
A: Enter all your assignment/exam grades with their weights as specified in your syllabus.

Q4: What's the difference between weighted and unweighted average?
A: Unweighted treats all components equally, while weighted accounts for their different importance.

Q5: Can I calculate what I need on the final exam?
A: Yes - enter your current grades and weights, then solve for your desired final grade.
