🗞️ What the Official Notice Says
As per the official notice (आवश्यक सूचना) dated 20 July 2026, the Mains Examination for selection to the posts of Avar Abhiyanta (Civil) / Sahayak Vikas Adhikari under the control of various departments, under Advertisement No. 08-Pariksha/2024, was conducted on 03 May 2026. Subsequently:
- The Provisional Answer Key of the said examination was uploaded on the Commission's website for candidates' perusal via the necessary information dated 04 May 2026.
- A link for registering objections (if any) against the Provisional Answer Key of the written examination's Master Set was uploaded on the Commission's website via the necessary information dated 08 May 2026.
- Now, after resolution (निराकरण) of the objections received against the Provisional Answer Key published on 04 May 2026, the Revised Answer Key (descriptive) of the Master Set of the said examination has been uploaded on the Commission's website, upsssc.gov.in, for candidates' perusal.

🎯 What "Revised After Objections" Means for You
This is the answer key that will actually be used — the provisional key was an invitation to challenge, and this Master Set is the Commission's final word after examining every objection filed. If an answer you challenged has been changed in this revised key, your objection (or someone else's on the same question) succeeded. If it hasn't, the Commission has upheld its original answer after review. Notably, as per the revised key, Question 97 carries the remark "FULL MARK" — meaning the Commission has decided to award full marks to all candidates on that question, a common resolution when a question is found flawed or ambiguous during objection review.
Match your recorded responses against the table below, and you'll have the most accurate self-score possible before the result is declared.

📊 What the Master Set Reveals About the Paper's Structure
Beyond serving as a scoring tool, the revised Master Set gives a clear picture of how the JE (Civil) Mains paper was actually distributed across subjects — useful both for candidates estimating their sectional performance and for future aspirants studying the pattern. Based on the 100 questions in the official revised key:
- Core Civil Engineering dominated the paper (roughly Q1–Q65). Strength of Materials, RCC and Steel design (Working Stress and Limit State Methods, prestressed concrete, column bases and effective length), Estimation & Costing, Soil Mechanics, Surveying, Transportation and Railway Engineering, Environmental Engineering, Building Materials & Construction, and Irrigation, Hydrology & Fluid Mechanics — together forming close to two-thirds of the paper.
- Computer and IT knowledge held a substantial block (Q66–Q80). Fifteen questions covered everything from Microsoft Excel and PowerPoint operations (Flash Fill, Allow Edit Ranges, Slide Master) to networking protocols (RTSP, NCP, RIP v2), machine learning basics (regression), IoT history (Kevin Ashton), big-data tooling (Hadoop at Yahoo!), and cyber fraud terminology (salami attacks) — a reminder that UPSSSC's technical papers now test digital literacy well beyond casual familiarity.
- Uttar Pradesh General Knowledge closed the paper (Q81–Q100). Twenty questions ranged from state industry and institutions (Modern Coach Factory in Raebareli, IIPR Kanpur, CISH Lucknow) to schemes and policy (Swadesh Darshan, UP Industrial Investment & Employment Promotion Policy 2022, the DASTAK campaign with UNICEF), to history and culture (Prayaga Praśasti by Harisena, the Gupta-era Dasavatara Temple at Deogarh, Raja Balwant Singh and Ramnagar) and current-affairs anchors like the state's first green hydrogen plant in Gorakhpur.
For future JE aspirants, the takeaway from this Master Set is straightforward: mastery of the core civil syllabus remains the backbone of the paper, but the combined 35 questions on computer knowledge and UP GK are far too large a block to treat as an afterthought.
🔁 The Provisional-to-Revised Journey — Why This Two-Step Process Exists
(General background on the answer-key objection mechanism used by UPSSSC and similar commissions — the specific dates below are from this notice; the rationale is general context.) The two-stage answer key process exists to make evaluation transparent and contestable. First, the Commission publishes a provisional key — in this case on 04 May 2026, the day after the exam — laying its intended answers open to scrutiny. Then an objection window follows — here, via the link uploaded on 08 May 2026 — during which candidates can formally challenge any answer they believe is wrong, typically with supporting justification. Every objection is then examined, and only after this resolution does the Commission publish the revised key that evaluation will actually be based on.
This process matters because even a single corrected answer can move a candidate across a cut-off line in a competitive examination, and a question awarded full marks — like Question 97 in this key — can lift every candidate's score simultaneously. The 20 July 2026 revised key is therefore not just a formality; it is the settled, evaluated-against version of the paper, and the eleven-week gap between the objection window and this release reflects the Commission working through the objections received.
🧮 How to Use This Revised Key to Estimate Your Score
- Pull out your recorded responses. Use the response sheet/attempt record from the 03 May 2026 Mains exam.
- Match question by question. Compare each of your answers against the revised Master Set answers in the tables above — remember that your question booklet series may have had questions in a different order than the Master Set, so match by question content, not just question number.
- Note Question 97. As per the revised key, this question carries "FULL MARK" — count it in your favour regardless of what you marked.
- Check the questions you had objected to. If the revised answer differs from the provisional one on any question you challenged, your objection was among those accepted.
- Treat your total as an estimate. The official marking scheme, negative marking details (if any), and final result computation are governed by the Commission's rules for this examination and are not restated in this notice — the authoritative score is the one UPSSSC declares with the result.
- Keep both keys if you saved the provisional one. Comparing the 04 May provisional key against this revised Master Set side by side is the quickest way to spot every answer that changed during objection resolution — and each change is a question where marks moved for someone.
⚙️ What Typically Happens After a Revised Answer Key
(General background on how UPSSSC-style recruitment processes usually proceed after this stage — not dates or commitments stated in this specific notice.) Once a revised answer key is published, the Commission generally proceeds to evaluate all candidates' responses against the final key and then declares the written examination result. Depending on the recruitment's structure, subsequent stages typically include document verification and, where applicable, further steps before the final selection list. Candidates should watch upsssc.gov.in for the result notification for Advertisement No. 08-Pariksha/2024, as no result date is mentioned in this answer-key notice.
