72nd BPSC Prelims Exam Pattern 2026: -0.33 Negative Marking & Option E Bubble Rules
Master the official 72nd BPSC Prelims examination architecture. 150 questions, 120 minutes, -0.33 negative marking deduction, and the critical Option E skip bubble rule on OMR sheets.
1. Official 150-Question Examination Structure
The 72nd BPSC Prelims examination consists of one composite paper: General Studies (GS). The paper contains 150 objective Multiple Choice Questions (MCQs) carrying 1 mark each, with a total duration of 2 hours (120 minutes).
Each question presents five distinct options: A, B, C, D, and E. While A through D contain substantive answer options, Option E is designated as "Not Attempted" (Skip).
| Parameter | Commission Rule | Impact on Candidate Strategy |
|---|---|---|
| Total Questions | 150 Questions | Must pace at 48 seconds per question |
| Total Marks | 150 Marks | 1 Mark awarded per correct answer |
| Test Duration | 120 Minutes (2 Hours) | Includes OMR bubbling time |
| Correct Answer | +1.00 Mark | Full credit for correct option (A, B, C, or D) |
| Incorrect Answer | -0.33 Mark (1/3rd) | Penalty deducted from gross score |
| Option E (Skip) | 0.00 Marks (No Penalty) | Must bubble Option E to skip safely |
| Unbubbled Question | -0.33 Mark Penalty | Leaving bubble blank is penalized as wrong! |
2. Negative Marking Penalty Mathematics (-0.33 / 1/3rd)
Since the 68th CCE, BPSC shifted to an authentic 1/3rd (-0.333) negative marking penalty. This means three incorrect answers completely wipe out the mark gained from one correct answer.
Blind guessing is mathematically fatal. However, intelligent elimination where you can eliminate 2 out of 4 options carries positive statistical expected value (+0.33 marks per gamble).
3. The Crucial Option E ("Not Attempted") Rule
BPSC introduced a mandatory bubbling rule to prevent OMR tampering. If you choose not to answer a question, you CANNOT leave the question row blank on your OMR sheet.
You MUST shade bubble E ("Not Attempted"). Shading Option E ensures zero marks are awarded and zero penalty is deducted. Leaving all bubbles blank in a row triggers an automatic -0.33 deduction!
Our online mock tests replicate the official Option E bubble mechanism so you practice marking Option E skips automatically during timed tests.
