đ„ How to Download the RPSC AE 2025 Answer Key (Model / Provisional)
Hereâs how you can download the RPSC AE answer key from the official portal:
Go to the RPSC official website: rpsc.rajasthan.gov.in RPSC
Look for a link / tab like âAnswer Key / Model Answer Key / AE Exam / Assistant Engineerâ in the âAnswer Keysâ / âStatic / Downloadâ section

The key is usually available in PDF format, set-wise (Set A, B, C, D)
Download and save a copy for reference
Open the PDF, check the answers against your marked responses, and estimate your score
If you have trouble locating the link, use the websiteâs search feature or check under âLatest News / Notifications.â Sometimes, RPSC updates the answer key in the âAnswer Keys / Model Keysâ section. (RPSCâs âAnswer Keysâ section shows keys for various exams)Â
đ§ź How to Use the Answer Key to Estimate Your Score
Once you have the answer key, follow these steps to estimate your marks:
Match your answers: Compare your chosen answers with those in the key for your exam set
Scoring scheme: Use the marking pattern specified in the exam notification (for prelims)
Correct vs Wrong: Mark full positive marks for correct answers, deduct negative marks (if any) for incorrect ones
Unanswered / Blank: No negative marking assumed (if policy allows)
Tally totals: Sum up correct scores minus penalties to get your estimated score
This estimate gives you an idea where you might stand before official results are out.
â Objection / Challenge Facility (If Available)
Many exams allow candidates to raise objections against the provisional answer key. Here’s how that usually works:
RPSC may publish a window during which candidates can submit objections online
Objections must be backed by documented proof / reference / justification
Sometimes an objection fee is charged per query
After reviewing objections, RPSC will finalize the answer key and declare results
The final key will override the provisional one
Keep an eye on RPSCâs Press Notes / Notifications section for an âOnline Objectionâ link.Â
đ Things to Verify & Keep in Mind
Correct exam set / paper code: Ensure you use the answer key corresponding to your exam set (A, B, C, D)
Question numbering / serial mapping: Sometimes keys use âQ No. / Res. No.â mapping â be cautious of shifts
Negative marking norms: Apply exactly as per RPSC rules (if â0.25 or â0.33 etc.)
Updates / revisions: RPSC may release a revised key if objections are accepted
Check cutoffs / merit later: The key helps estimate, but final results & cutoffs depend on many factors (normalization, tie rules etc.)
