OPSC OCS GS Paper 1 Marking Scheme & Negative Marking
- Each GS Paper-I question carries equal marks. With 100 questions for 200 marks, each correct answer is worth 2 marks.
- For every wrong answer, a negative marking of one-third (1/3) of the marks assigned to that question is deducted — i.e. approximately 0.67 marks per wrong answer in GS Paper-I.
- Unattempted questions carry no penalty (zero marks deducted).
- Marking more than one option for a question is treated as a wrong answer.
How to Calculate Your Score Using the GS Paper 1 Answer Key
Once the official answer key is out, estimate your GS Paper-I score with this simple formula:
Score = (Correct × 2) − (Wrong × 0.67)
- Count the number of correct answers and multiply by 2.
- Count the number of wrong answers and multiply by 0.67.
- Subtract the negative total from the correct total.
- Leave out unattempted questions — they neither add nor deduct marks.
This gives a close estimate of your probable GS Paper-I score even before the result is declared.
