Formula Explained

Calculation Formula

The formula used is:

Final Score = (Correct Answers × 1) - (Incorrect Answers × 1/3)

Where:

Correct Answers = Number of questions answered correctly
Incorrect Answers = Number of questions answered incorrectly

This formula accounts for the negative marking scheme where each incorrect answer deducts 1/3 of a mark from your total score.

Worked Example

Let's say you took an exam with 50 questions. You answered 40 questions correctly and 10 questions incorrectly.

Using the formula:

Final Score = (40 × 1) - (10 × 1/3) = 40 - 3.33 = 36.67

So your final score would be 36.67 out of 50.

Interpreting Results

The calculator provides three key metrics:

Raw Score: Number of questions answered correctly
Negative Marks: Marks deducted for incorrect answers
Final Score: Your adjusted score after negative marking

Use these results to:

Compare your performance with others
Identify areas where you need improvement
Determine if you've met the passing criteria

Note

Remember that negative marking can significantly impact your final score. It's important to balance speed and accuracy to maximize your performance.
