1. What is a Marks Calculator by Answer Key?

Definition: This calculator computes total marks based on correct answers in different sections and their respective weights.

Purpose: It helps educators and students calculate weighted scores for exams with multiple sections.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M = \sum C_i \times W_i \]

Where:

\( M \) — Total marks (dimensionless)
\( C_i \) — Correct answers for section i (dimensionless)
\( W_i \) — Weight per question (dimensionless)

Explanation: For each section, multiply the number of correct answers by the weight per question, then sum all sections.

3. Importance of Weighted Mark Calculation

Details: Different exam sections often carry different weights to reflect their importance or difficulty level.

4. Using the Calculator

Tips: Enter correct answers for each section and their respective weights. Leave sections blank if not applicable.

5. Frequently Asked Questions (FAQ)

Q1: What if my exam has more than two sections?
A: You can add more sections by extending the form or calculate sections separately and sum the results.

Q2: How do I determine the weight per question?
A: Check your exam instructions. Weight is typically the marks assigned to each question in that section.

Q3: Can I use decimal values for correct answers?
A: No, correct answers must be whole numbers. Partial credit should be reflected in the weight.

Q4: What if sections have different numbers of questions?
A: The calculator automatically accounts for this through the correct answers count and weights.

Q5: How do I calculate percentage scores?
A: Divide the total marks by the maximum possible marks (sum of all questions' weights) and multiply by 100.
