Objection Process

OSSC has invited online objections against the tentative answer key. Candidates who find a discrepancy should challenge the specific question through the official portal before 2 November 2026. Objections submitted after the deadline or outside the prescribed online facility may not be considered.

1. Open the tentative answer key objection link on the official OSSC website.
2. Log in using your roll number and date of birth.
3. Open the answer key and objection section.
4. Select the question you want to challenge.
5. Enter the objection details and the answer you believe is correct.
6. Upload valid supporting documents or reference material for the challenge.
7. Review the objection carefully and submit it online by 2 November 2026.
8. Save the submission acknowledgement, if the portal generates one.

According to the published update, no objection fee was mentioned for submitting challenges. Candidates should still verify the fee conditions shown on the official objection portal before completing a submission, since the portal display is the final authority. Unsupported objections, filed without reference material, may not be accepted.

How to Calculate Marks Using the Answer Key

The provisional key lets candidates estimate their preliminary examination score before the result is declared. According to the examination information for CTSRE-2025, the preliminary paper carries 150 marks with negative marking of one-fourth of the marks assigned to an incorrectly answered question.

Estimated Marks = Correct Answers x 1 – Incorrect Answers x 0.25. For example, 100 correct answers and 20 incorrect answers would give an estimated score of 95 marks. This is only an estimate: the final evaluation may change if the commission revises any answers after reviewing objections. Candidates should confirm the marking scheme from the official examination instructions before calculating scores.

Exam Pattern

The preliminary examination shortlists candidates for the next stage of the CTSRE-2025 recruitment. Candidates should refer to the official notification for the complete syllabus, question distribution and evaluation conditions.

Final Answer Key and Result

The key released on 30 October 2026 is tentative and should not be confused with the final answer key. After the objection window closes on 2 November 2026, OSSC will examine the representations submitted by candidates and may revise answers where objections are accepted. The final answer key will then be published under the commission’s recruitment procedure. The preliminary result and the list of candidates shortlisted for the next stage have not been announced yet; candidates should monitor the official OSSC website for the result PDF, cut-off marks and the Main Examination schedule.
