This is the final answer key for the Sr. Scientific Officer (Home Department) Competitive Examination 2024, conducted by the Rajasthan Public Service Commission (RPSC), Ajmer. The exam, held on 14 May 2025, tested candidates on Serology Division subjects covering Part B (Biochemistry) and Part C (Forensic Science). The question paper comprised 150 multiple-choice questions, and this official answer key was published on the RPSC website on 3 July 2026.
This is a final answer key, meaning it reflects all corrections and decisions on objections filed by candidates during the provisional phase. Candidates can use this key to estimate their score by matching their responses against the answers provided. The marking scheme (if stated in the original notification) determines the credit per question; typically, one mark is awarded per correct answer with no negative marking unless specified.
Candidates who wish to challenge any answer in the final key or who raised objections during the provisional phase can refer to the objection result notification separately published by RPSC. The final answer key is binding for score calculation and merit list preparation. Results and the subsequent merit list are typically declared within 4–8 weeks of answer key finalization, though the exact timeline depends on the volume of objections and administrative processing.
All candidates are advised to download this key from the official RPSC website, cross-check their responses, and await the official result announcement for next steps such as document verification, interview scheduling (if applicable), or appointment.

Frequently Asked Questions
Where can I download the final answer key?▾
The final answer key is available on the official RPSC website at rpsc.rajasthan.gov.in. Search for 'Sr. Scientific Officer Home Dept. Serology Division Answer Key' or navigate to the 'Answer Keys' section. The PDF (dated 3 July 2026) contains all 150 questions and their correct responses.
Is this a provisional or final answer key?▾
This is the final answer key, published on 3 July 2026. It incorporates all corrections and decisions made on objections filed during the provisional phase. This key is now binding for score calculation and merit list generation.
How do I estimate my score using this answer key?▾
Match your responses (from the admit card or your memory) against the correct answers listed in the key for all 150 questions. Multiply the number of correct answers by the marks per question (as stated in the official notification, typically 1 mark). Subtract any penalty marks if negative marking applies. This gives your estimated score.
Can I still challenge any answer in the final key?▾
Typically, objections are accepted only during the provisional answer key period. Once the final key is published, direct challenges are generally not entertained unless RPSC issues a specific re-opening window. Check the RPSC website for any notification regarding final key objections or appeal procedures.
What is the objection fee and how is it refunded?▾
The objection fee (if applicable) is stated in the official examination notification. It is typically charged per question challenged. If your objection is upheld and the answer is corrected, the fee is refunded; otherwise, it is forfeited. Check the final objection result notice for refund status.
When will the final result and merit list be published?▾
Results are typically declared 4–8 weeks after the final answer key is published. For this exam, with the key dated 3 July 2026, expect the result by mid-to-late August 2026 (as per RPSC's standard timeline). Check the RPSC website regularly for the official result announcement.
What happens after my result is declared?▾
Once results are declared, qualified candidates are called for document verification and, if applicable, interview or viva-voce. The final selection is made based on marks and interview performance. Selected candidates proceed to the appointment order stage.
Can I download the question paper and my scanned responses?▾
Yes. RPSC typically uploads the question paper and candidate response sheets (scanned images) on their portal around the same time as the provisional answer key. Log into your candidate account to download these documents for verification and objection purposes.
Is there a deadline to download the answer key?▾
The answer key remains available on the RPSC website indefinitely for reference. However, to file objections (if allowed), you must act within the specified window announced by RPSC, typically 5–7 days from the publication of the provisional key. Since this is the final key, check for any additional challenge windows in official notices.
How are objections decided and by whom?▾
RPSC appoints a subject expert committee to review objections with supporting evidence. If an objection is found valid, the answer is corrected and all affected candidates are credited. The decision is final and published in the form of the final answer key and a separate objection result notice with subject-wise corrections listed.
