CUET PG Life Science Answer Key: How to Calculate Your Marks Correctly

 After the CUET PG Life Science exam, the next important step for students is checking the official answer key. The answer key helps you understand how many questions you answered correctly and what your expected score might be.

Let’s see how you can calculate your marks accurately.

What Is the CUET PG Answer Key?

The answer key is an official document released after the exam that contains the correct answers for all questions asked in the paper.

Using the answer key, students can:

  • Verify their responses

  • Estimate their marks

  • Identify incorrect answers

  • Predict their possible score range

This helps students prepare mentally before the result announcement.

Step 1: Download the Official Answer Key

Once the answer key is released:

  • Visit the official CUET PG website

  • Download the answer key for the Life Science paper

  • Open the question paper along with the answer key

Make sure you use the correct paper code while checking answers.

Step 2: Compare Your Answers

Go through each question and compare it with the official answer key.

While checking, classify each question into three groups:

  • Correct answers

  • Incorrect answers

  • Unattempted questions

This makes score calculation easier.

Step 3: Apply the CUET PG Marking Scheme

CUET PG generally follows this scoring system:

  • Correct answer: +4 marks

  • Wrong answer: –1 mark

  • Unattempted question: 0 mark

Understanding this pattern helps you estimate marks correctly.

Step 4: Calculate Your Score

Use this simple formula:

Estimated Score = (Correct Answers × 4) – (Wrong Answers × 1)

Example:

If you have:

  • 48 correct answers

  • 12 incorrect answers

Then your estimated score will be:

(48 × 4) – (12 × 1) = 192 – 12 = 180 marks

This gives a rough estimate of your performance.

Step 5: Check Possibility of Challenging the Answer Key

Sometimes students may feel a particular answer in the key is incorrect.

In such cases, the exam authority usually allows students to:

  • Submit objections

  • Provide supporting references

  • Challenge specific answers

After reviewing objections, a final answer key is released.

Final Advice

The answer key helps you estimate your score, but the official result will be the final confirmation.

Use the predicted score to start planning your next steps, including university research and counselling preparation.
