Important Rules for Objection (From OSSC Notice)

• Every objection is decided on merit. The number of candidates who object to the same question does not change the result.
• If another candidate has already objected to an answer and you have no new facts or arguments, you do not need to file the same objection again.
• Candidates should check the OSSC website often for any new update.

Objection fee: The sources I checked do not mention any fee. If any fee is asked on the portal, it will be shown on the page. Please read the instructions on the objection page carefully and pay only on the official portal.

OSSC CTSRE Prelims Exam Pattern 2026

How to Calculate Your Marks Using the Answer Key?

1. Download your response sheet and the tentative key.
2. Match each answer you marked with the key.
3. Count your correct, wrong and not attempted questions.
4. Use this formula: Estimated Marks = Correct Answers – (0.25 x Wrong Answers)
5. Not attempted questions get no marks and no deduction.

Example (for understanding only): If a candidate has 100 correct and 28 wrong answers, marks = 100 – (0.25 x 28) = 100 – 7 = 93 out of 150.

Important: This is only an estimate. OSSC may change the key after objections, and normalisation may be used if the exam was held in more than one shift. Your final marks can be different. Qualifying cut-off marks are decided by OSSC as per category rules.
