1. What Is Aggregate Score?

Aggregate Score is a weighted average calculation used to determine overall performance across multiple subjects or components, where each component contributes differently to the final result based on its assigned weight.

2. How Does The Calculator Work?

The calculator uses the aggregate score formula:

\[ \text{Aggregate Score} = \frac{\sum (\text{Subject Score} \times \text{Weight})}{\sum \text{Weights}} \]

Where:

\( \text{Subject Score} \) — Individual score for each subject (unitless)
\( \text{Weight} \) — Relative importance or credit value of each subject (unitless)
\( \sum \) — Summation of all weighted scores and weights

Explanation: This formula calculates a weighted average where subjects with higher weights contribute more significantly to the final aggregate score.

3. Importance Of Aggregate Score Calculation

Details: Aggregate scores are crucial for academic grading systems, performance evaluations, scholarship determinations, and admission processes where different subjects or components have varying levels of importance.

4. Using The Calculator

Tips: Enter scores and weights for three subjects. All values must be non-negative numbers. The calculator will compute the weighted aggregate score based on the input values.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between aggregate score and average?
A: Aggregate score is a weighted average where different subjects have different importance, while a simple average treats all subjects equally.

Q2: How are weights determined?
A: Weights are typically determined by credit hours, course difficulty, or institutional policies regarding subject importance.

Q3: Can I calculate aggregate score for more than three subjects?
A: Yes, the same formula applies. You would simply add more subject-score and weight pairs to the calculation.

Q4: What if the total weight is zero?
A: The calculation is undefined if total weight is zero, as division by zero is mathematically impossible.

Q5: How is aggregate score used in education?
A: It's commonly used for GPA calculations, determining class ranks, scholarship eligibility, and university admissions.
