How to Calculate Your Marks Using CDS 2 2025 Answer Key

Before the release of the UPSC CDS 2 2025 answer key, make sure to be aware of the marking scheme of the concerned authorities. 

There are some points a candidate must know: 

1. For each correct answer, +1 mark will be awarded. 

2. There is a negative marking of ⅓ marks for every incorrect answer.

3. If any question is unattempted, then there is no negative marking. 

4. Make sure to cross-check the answer from the official answer key. 

5. Calculate the total number of correct and incorrect answers. 

6. For each correct answer, multiply each correct answer by the marks awarded for each. 

7. For each incorrect answer, multiply it by the negative marking. 

8. The last step to get the final score is to deduct the marks of incorrect answers from the correct marks. Then the final score will be obtained. 

For Example: 

1. For IMA, INA, AFA

• English

• Questions: 120

• Marks per Question: 0.83

• Negative Marking: –0.27

• Total: 100 marks

• General Knowledge (GK)

• Questions: 120

• Marks per Question: 0.83

• Negative Marking: –0.27

• Total: 100 marks

• Elementary Mathematics

• Questions: 100

• Marks per Question: 1

• Negative Marking: –0.33

• Total: 100 marks

 Total = 300 Marks

2. For OTA (Officers’ Training Academy)

• English → 120 Qs (100 marks)

• GK → 120 Qs (100 marks)

Total = 200 Marks

Final Score = (Correct Answers × Marks per Question) – (Wrong Answers × Negative Marks)

Example (IMA candidate):

• English: 80 correct, 20 wrong → (80×0.83) – (20×0.27) = 66.4 – 5.4 = 61

• GK: 60 correct, 30 wrong → (60×0.83) – (30×0.27) = 49.8 – 8.1 = 41.7

• Math: 70 correct, 20 wrong → (70×1) – (20×0.33) = 70 – 6.6 = 63.4

Total = 61 + 41.7 + 63.4 = 166.1 / 300
