1. What is a Percentage Calculator by Marks?

Definition: This calculator determines the percentage score based on marks obtained out of total possible marks.

Purpose: It helps students, teachers, and professionals quickly calculate percentage scores for tests, exams, or evaluations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \% \) — Percentage score
• \( Marks \) — Marks obtained (unitless)
• \( Total \) — Total possible marks (unitless)

Explanation: The marks obtained are divided by total marks and 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 evaluation systems with varying total marks.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What if I get more marks than the total?
A: The calculator will not display a result if marks exceed the total, as this is mathematically impossible.

Q2: Can I calculate percentage for multiple tests?
A: Yes, sum all marks obtained and all total marks first, then use those totals in the calculator.

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

Q4: Can I use this for weighted averages?
A: No, this calculates simple percentages. For weighted averages, multiply each component by its weight first.

Q5: What if my test has bonus marks?
A: Include bonus marks in both the obtained marks and total marks for accurate calculation.
