Published 4 Jul 2026 · Updated 5 Aug 2026
This is the final answer key for the Rajasthan Public Service Commission (RPSC) Sr. Scientific Officer (Home Department) Competitive Examination 2024, conducted for the Serology Division (Part A – Zoology and Part C – Forensic Science). The exam was held on 14 May 2025. The final answer key was published on the official RPSC website on 3 July 2026 and contains 150 questions with their correct responses (options 1–4), marked as per the question paper uploaded on the RPSC portal.
Candidates can use this final answer key to verify their responses and estimate their likely score by comparing their answers against the official solutions. Each correct answer typically carries one mark in PSC examinations, though the exact marking scheme should be confirmed from the official notification. As this is the final answer key, it supersedes any provisional key that may have been published earlier.
The objection process for PSC answer keys is normally closed once the final key is released. If candidates wish to challenge any answer during the provisional period (if one was issued), they must submit objections within the notified window with the required fee per question, providing documentary evidence or legal precedent. The RPSC evaluates objections and amends the final key if warranted. Results are typically declared after the final answer key is published, following the standard PSC result publication timeline.
Candidates are advised to download the answer key directly from the official RPSC website (rpsc.rajasthan.gov.in) and cross-verify their performance. The organisation will announce the written examination result and subsequent stages (interview, if applicable) as per its notification schedule.
