Tips to Manage Negative Marking in Government Exams

- For UPSC Prelims (−2/3 penalty), you need 3 correct for every 2 wrong. Skip if unsure.
- Track your accuracy using this calculator after each mock test to decide your optimal attempt strategy.
- Unattempted questions have zero penalty in SSC, UPSC, Railway, and Banking exams.
