What Information is Available in the RSSB Lab Assistant Answer Key 2026 PDF?
Candidates often wonder what exactly the answer key PDF contains. Here is what you will find inside:
The document clearly mentions the name of the exam conducting body (RSSB), the exam name (Lab Assistant Examination 2026), the post name, exam date, exam code, question numbers along with their correct options, and the date on which the answer key was released. Each question’s correct answer is listed booklet-series wise so that candidates can match their specific version of the paper.
How to Calculate Your Score Using the RSSB Lab Assistant Answer Key 2026
Before you panic or celebrate, let us walk you through the exact marking scheme so that you calculate your score correctly.
For Science Subject: Each correct answer carries +2 marks. Each incorrect answer carries a deduction of 0.33 marks (i.e., 1/3 of 2 marks).
For Geography Subject: Each correct answer carries +1 mark. Each incorrect answer carries a deduction of 0.33 marks (i.e., 1/3 of 1 mark).
Unattempted or blank answers carry no marks — neither positive nor negative.
Score Calculation Formula:
Total Score = (Number of Correct Answers × Subject Mark) – (Number of Incorrect Answers × 1/3 of Subject Mark)
Example for Science: If you got 70 correct and 20 incorrect: (70 × 2) – (20 × 0.67) = 140 – 13.4 = 126.6 marks
Use this formula for both subjects separately and then add them up for your total estimated score.
RSSB Lab Assistant 2026 – Minimum Qualifying Marks (Category-Wise)
Scoring well is important, but first you need to cross the qualifying threshold set by RSSB. Candidates must secure the following minimum marks based on their category:
| Category | Minimum Qualifying Marks |
|---|---|
| SC / ST | 35% of total marks |
| OBC / General / Others | 40% of total marks |
Only those who meet or exceed these minimum qualifying marks will have their answer sheets considered further for result declaration. If your estimated score is falling short of these benchmarks, now is also the time to review your objections carefully.
RSSB Lab Assistant Expected Cut Off 2026
The official cut-off will be released alongside the result. Until then, based on previous year trends and this year’s exam difficulty level, here are the expected category-wise cut-off marks:
| Category | Male (Expected) | Female (Expected) |
|---|---|---|
| UR (General) | 128 – 135 | 114 – 122 |
| OBC | 115 – 122 | 106 – 112 |
| SC | 90 – 95 | 78 – 82 |
| ST | 80 – 86 | 75 – 80 |
Keep in mind that these are expected ranges, not official figures. The actual cut-off depends on overall candidate performance, number of vacancies, and the final answer key after objections are resolved.
How to Raise Objections Against RSSB Lab Assistant Answer Key 2026
One of the most important features of the provisional answer key is the opportunity to challenge any incorrect answers. RSSB has opened a 2–3 day objection window on the SSO Rajasthan portal. Here is how to raise a valid objection step by step:
Step 1: Visit the official RSSB website at www.rssb.rajasthan.gov.in.
Step 2: Go to “Candidate Corner” and then click on “Online Question Objections.”
Step 3: Select “Lab Assistant Recruitment Examination 2026” from the list.
Step 4: Download the provisional answer key and review it carefully against the Master Question Paper.
Step 5: Identify all questions where you believe the official answer is incorrect.
Step 6: Click on the “Raise Objection” link, select the question number, enter your suggested correct answer, and provide a clear and valid reason.
Step 7: Upload documentary proof — this must be from standard books, government publications, or authenticated reference materials. Objections submitted without valid proof are automatically rejected.
Step 8: Pay the objection fee of Rs. 100 per question (non-refundable) through either the e-Mitra payment gateway or by visiting an e-Mitra kiosk using your SSO ID.
Step 9: Submit the objection and download your objection receipt. Keep it safe for future reference.
Important Note: You must file objections only based on the Master Question Paper issued by RSSB. Do not raise objections based on memory alone — always back them with proper reference material including book name, author, publisher, year of publication, and the relevant page number.
RSSB Lab Assistant Answer Key 2026 – Objection Fee Details

|---|---|
| e-Mitra Payment Gateway | Pay online using SSO ID |
| e-Mitra Kiosk | Visit nearest e-Mitra centre to pay |
| Fee Per Question | Rs. 100 (Non-refundable) |
The fee is charged per objection regardless of whether the objection is accepted or rejected. So make sure you only raise objections where you have solid, documented proof.
Why Is the Lab Assistant Answer Key 2026 So Important?
If you have never appeared in a major state-level exam before, you might wonder why everyone is so eager to check the answer key. Here is the thing — the answer key serves a very real and practical purpose for every candidate.
It lets you calculate an approximate score before the official result is declared, which could be weeks away. This helps you decide whether to start preparing for other exams simultaneously or focus your energy on the document verification stage. It also brings transparency to the recruitment process. RSSB publicly publishes the correct answers so that every candidate — and their family — can verify the process independently. And importantly, the objection window gives you the right to challenge any answer you believe is incorrect. This is a democratic check on the evaluation process and has led to corrections in previous years too.
Simply put, the answer key removes the guesswork and the anxiety that comes with waiting weeks for a result you have no visibility into.
What Happens After the Provisional Answer Key?
Here is what the timeline looks like from here on:
Once the objection window closes, RSSB will review all submitted objections along with the supporting documentation. After verification, the board will publish the Final Answer Key. Once the final key is released, no further challenges are accepted under any circumstances.
Based on the final answer key, the RSSB Lab Assistant Result 2026 is expected to be released in June or July 2026. The result will be published in PDF format at rssb.rajasthan.gov.in and will carry the roll numbers of candidates who have qualified for the next stage, which is Document Verification.
Along with the result, RSSB will also release the official category-wise cut-off marks. Candidates who score above the cut-off will be included in the Merit List and called for document verification.
