State Public Service Commission (PSC) examinations follow a rigorous multi-tier selection structure designed to evaluate candidates from baseline general screening up to advanced analytical and administrative capability. The Preliminary examination functions strictly as an objective-type screening test utilizing multiple-choice questions to filter candidates. In contrast, the Main examination transitions into a comprehensive descriptive or written format requiring deep analytical reasoning, structural articulation, and multi-disciplinary evaluation. Grasping these foundational format differences enables aspirants to align their study timelines, master objective elimination techniques, and cultivate rigorous essay-writing proficiency.

The Preliminary examination serves solely as a screening or filtering mechanism to eliminate non-serious candidates. It decides who qualifies for the Mains.
Correct Answer: c) They are not counted in the final merit list
Explanation:
Marks scored in the Preliminary examination are qualifying in nature for the next stage and are completely discarded when calculating the final merit list.
Correct Answer: c) Objective type (Multiple Choice Questions)

Correct Answer: b) Descriptive/Subjective type
Explanation:
The Mains examination is a conventional written exam consisting of descriptive and subjective type questions requiring essay-style answers.
Correct Answer: b) Yes, they are combined with the Interview marks
Explanation:
The final merit list is determined by adding the marks obtained in the Mains examination (merit-based papers) and the Personality Test (Interview).
Correct Answer: b) Answers are evaluated through OMR (Optical Mark Recognition) scanning
Explanation:
Because the Prelims are objective, candidates mark their answers on OMR sheets, which are then rapidly evaluated by computerized scanners.

Explanation:
Mains answers are descriptive and therefore manually evaluated by human experts who grade based on articulation, factual accuracy, and presentation.
Correct Answer: b) Yes, marks are typically deducted for incorrect answers (e.g., 1/3rd)
