1. What is a Subject Percentage Calculator?

Definition: This calculator determines the percentage score obtained in a subject based on marks achieved and maximum possible marks.

Purpose: It helps students and educators quickly calculate percentage scores for tests, exams, or assignments.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \% \) — Percentage score
• \( \text{Marks} \) — Marks obtained (unitless)
• \( \text{Max} \) — Maximum possible marks (unitless)

Explanation: The marks obtained are divided by the maximum marks, then multiplied by 100 to convert to percentage.

3. Importance of Percentage Calculation

Details: Percentage scores provide a standardized way to compare performance across different tests or subjects with varying maximum marks.

4. Using the Calculator

Tips: Enter the marks obtained and maximum possible marks. Both values must be positive numbers, and marks cannot exceed maximum marks.

5. Frequently Asked Questions (FAQ)

Q1: What if I get more marks than the maximum?
A: The calculator will only accept marks that are less than or equal to the maximum marks entered.

Q2: Can I calculate percentage for multiple subjects?
A: This calculator is for single subject percentage. For multiple subjects, you would need to sum all marks and maximum marks first.

Q3: How precise are the results?
A: Results are shown to 2 decimal places for accuracy.

Q4: What if I enter zero for maximum marks?
A: The calculator requires maximum marks to be greater than zero (division by zero is undefined).

Q5: Does this calculator round the percentage?
A: No, it shows the exact calculated value. You can round manually if needed.
