⚖️ 3. Negative Marking Mathematical Penalty & Normalization
To ensure standardized assessment across multiple shifts, UPSC implements rigorous scoring protocols:
- Negative Marking Penalty: For every incorrect objective answer, 0.25 to 0.33 of the assigned marks will be deducted. Unattempted questions carry zero penalty.
- Shift Normalization Formula: Because multi-shift examinations feature varying levels of paper difficulty, raw scores are normalized using standard deviation formulas to derive equitable normalized percentiles.
- Tactical Strategy: Candidates are advised against blind guessing. Maintaining an accuracy rate above 85% is essential to avoid negative penalty erosion on competitive cutoffs.
