- Final Merit List and Recommendation for Appointment
The written examination will be used to shortlist candidates for the physical test. Physical test marks will not be added to the merit score. The final merit list will be prepared on the basis of marks obtained in the main written examination, category-wise and in descending order of merit.
Exam Pattern
The written examination will be conducted at the Matriculation or equivalent level and will consist of objective-type questions. There will be two question papers.
| Paper | Subjects | Questions | Marks | Duration |
|---|---|---|---|---|
| Paper I | Reasoning and Analytical Ability: 50 marks; English Grammar, Comprehension and Translation: 30 marks; Hindi Grammar: 20 marks | 100 | 100 | 90 minutes |

- Each correct answer carries 1 mark.
- 0.25 marks will be deducted for every wrong answer in both papers.
- The examination will be conducted using an OMR answer sheet.
- Candidates must secure at least 30% marks separately in each question paper to qualify for the Physical Standard Test.
- Approximately three times the number of advertised vacancies in each reservation category will be shortlisted for the physical test, subject to the applicable cut-off.
- In case of multiple shifts or multiple question papers, normalized marks may be calculated using the Equi-Percentile Method.
Minimum Qualifying Marks for Final Merit
| Category | Minimum Qualifying Marks |

| Unreserved / General | 40% |
| Backward Class (BC) | 36.5% |
| Extremely Backward Class (EBC) | 34% |
| SC, ST and other reserved categories | 32% |
The final merit list will be prepared category-wise based on the marks obtained in the main written examination. If candidates obtain equal marks, preference will first be given to the older candidate. Further ties will be resolved based on educational qualification and then the alphabetical order of the candidate’s name as recorded in the Class 10 certificate.
