Understanding the Recruitment and the Role of GWSSB
The Gujarat Water Supply and Sewerage Board plays a crucial role in managing water supply and sanitation infrastructure across the state. The Chief Scientific Officer (Class-1) and Scientific Officer (Class-2) positions are specialized scientific roles that support technical, research, and quality-related functions within the board. These posts require candidates with strong scientific backgrounds, typically involving qualifications in relevant science or engineering disciplines.
The written examination tested candidates across a broad syllabus relevant to these roles, featuring a total of 200 questions. The question papers were issued in multiple series—MASTER, A, B, C, and D—to maintain the integrity of the examination process and reduce the possibility of malpractice. Each series contained the same set of questions but arranged in a different order. This is standard practice in large-scale competitive examinations conducted by bodies like GPSC.
The release of the final answer key on 30 July 2026, more than two months after the exam, indicates that the commission carefully evaluated any objections raised against the provisional key (if one was issued). While specific details about the provisional key release date and the exact objection window are not mentioned in the available documents, the final key represents the conclusive version that will be used for evaluating OMR sheets or response sheets.
Overview of the GPSC Final Answer Key 2026
Here is a quick snapshot of the key information:
- Conducting Body: Gujarat Public Service Commission (GPSC)
- Posts: Chief Scientific Officer, Class-1 (GWSSB) and Scientific Officer, Class-2 (GWSSB)
- Advertisement Numbers: 106/2025-26 and 130/2025-26 respectively
- Exam Date: 20 May 2026
- Final Answer Key Release Date: 30 July 2026
- Release Location: Gandhinagar
- Total Questions: 200 (Question numbers 1 to 200)
- Question Paper Series: MASTER, A, B, C, and D
Candidates should note that the final answer key is series-specific. Using the wrong series while checking answers can lead to completely incorrect score calculations. Always refer to the series printed on your question booklet or admit card.
Cancelled Questions and Their Implications
One of the most important aspects of any final answer key is the list of cancelled questions. GPSC has cancelled four questions in each applicable series. These are typically marked with an asterisk (*) in the official document. Because the question order differs across series, the cancelled question numbers vary:
- MASTER Series: Questions 33, 37, 126, and 141
- Series A: Questions 33, 37, 126, and 141
- Series B: Questions 8, 12, 101, and 116
- Series C: Questions 83, 87, 176, and 191
- Series D: Details not specified in the available summary
Important scoring note: In competitive examinations, cancelled questions are generally treated in a candidate-friendly manner. Most commissions, including GPSC in standard practice, award marks for cancelled questions to all candidates who appeared for the exam, regardless of whether they attempted them or not. However, the exact marking scheme for this particular examination is not explicitly stated in the answer key summary. Candidates should verify the official GPSC notification or accompanying circular before adding marks for cancelled questions.
Questions with Multiple Correct Answers
In addition to the cancelled questions, the final answer key recognizes one question in most series as having two acceptable correct options (A and B). This occurs when the question wording, options, or subject matter allows for more than one valid interpretation based on the prescribed syllabus or official sources.
The details are as follows:
- MASTER Series: Question 154 – Accepted answers A & B
- Series A: Question 179 – Accepted answers A & B
- Series B: Question 154 – Accepted answers A & B
- Series C: Question 129 – Accepted answers A & B
- Series D: Not specified
Candidates who marked either of the accepted options for these questions will receive full credit. Those who marked a different option will not. When calculating your score, treat these questions carefully and award yourself marks if you selected one of the two accepted answers.
How to Download the Official GPSC Final Answer Key 2026
Downloading the authentic final answer key from the official source is essential. Follow these steps carefully:
- Visit the official website of the Gujarat Public Service Commission at gpsc.gujarat.gov.in.
- On the homepage, look for the “Answer Key” section or the “Notifications / Latest Updates” area.
- Search for the relevant advertisement numbers—106/2025-26 for Chief Scientific Officer or 130/2025-26 for Scientific Officer—or directly for the final answer key related to the 20 May 2026 examination.
- Click on the link for the final answer key PDF.
- Identify your question booklet series (MASTER, A, B, C, or D).
- Download and save the PDF for offline reference and future verification.
- Cross-check every response carefully against the official key for your specific series.
Candidate Tip: Before calculating your score, keep your original question paper/response record beside the final answer key. This reduces the possibility of accidentally comparing your answers with a different paper series.
Avoid relying solely on third-party websites for the actual answer key content. While educational portals may provide helpful summaries and guidance, the PDF hosted on the GPSC website is the only authoritative document.
How to Check Your Answers Correctly
- Identify your series: Confirm whether your paper was MASTER, A, B, C or D.
- Match question numbers: Compare the question number in your paper with the same number in the relevant final key.
- Mark correct responses: Make a separate list of questions where your answer matches the final key.
- Check cancelled questions: Identify whether your series contains any cancelled questions.
- Check multiple-answer questions: Carefully verify whether your selected option is one of the accepted answers.
- Apply the official marking scheme: Do not assume a marking rule without checking the applicable notification.
- Keep a record: Save your estimated score for comparison with the official result.
Estimating Your Score and Preparing for the Next Stage
Once you have the final answer key, calculating an approximate score becomes straightforward. Most GPSC examinations follow a marking pattern of +1 for each correct answer and negative marking (often 0.33 or 0.25) for incorrect responses, though the exact scheme should be confirmed from the original advertisement or exam notification. Award yourself marks for cancelled questions as per the commission’s policy, and give credit for the multiple-correct questions if you chose an accepted option.
After estimating your score, compare it with expected cut-off trends from previous similar recruitments if available. Keep in mind that final cut-offs depend on multiple factors, including the number of vacancies, the difficulty level of the paper, the performance of the candidate pool, and reservation norms.
The release of the final answer key usually precedes the declaration of results. Candidates who clear the written examination cut-off can expect further stages such as document verification, interviews, or other assessments as outlined in the original recruitment notification. It is advisable to keep all original documents ready—educational certificates, caste certificates (if applicable), experience proofs, and identity documents—so that there is no delay if shortlisted.
What Candidates Should Do After the Final Answer Key
| Step | What to Do |
|---|---|
| 1. Check Key | Verify answers using your own question series. |
| 2. Estimate Score | Calculate your probable marks using the applicable marking rules. |
| 3. Preserve Documents | Keep the answer key and your score calculation safely stored. |
| 4. Monitor Result | Regularly check official GPSC updates. |
| 5. Prepare Further | Keep educational, identity and other required documents ready for subsequent stages. |
Important Instructions for Candidates
- Always match answers using only your own question series.
- Do not assume the marking policy for cancelled questions; confirm it officially.
- The final answer key already incorporates the resolution of any challenges raised earlier. No further objections are typically entertained after the final key is published.
- Save both the digital and printed copies of the answer key and your calculated score sheet for personal records.
- Regularly check the official GPSC website for updates regarding results, cut-offs, and subsequent selection stages.
- Stay away from unofficial WhatsApp groups or social media claims that may circulate incorrect keys or cut-off predictions.
Why the Final Answer Key Matters
For serious aspirants, the final answer key is more than just a list of correct options. It brings transparency to the evaluation process and allows candidates to identify their strengths and weak areas. Even if a candidate does not clear the current recruitment, analyzing the key helps in understanding the commission’s preferred approach to questions and prepares them better for future attempts.
The gap of over two months between the examination (20 May 2026) and the final key release (30 July 2026) is not unusual for state public service commissions that handle large volumes of objections and technical scrutiny. Candidates are encouraged to use this waiting period productively—either by preparing for possible interviews or by focusing on other ongoing recruitments.
