Delhi Cantonment Board Junior Engineer Answer Key 2026

Overview of Delhi Cantonment Board Junior Engineer Answer Key 2026

The Delhi Cantonment Board conducted the Junior Engineer Examination on October 25, 2026, across designated centers. Following the successful completion of the written test, the board has issued the provisional answer key to maintain transparency in the selection procedure. Candidates who appeared for the exam can now cross-verify their responses against the official solutions provided by the examination authority.

Understanding Provisional vs Final Answer Key

An answer key serves as an official document containing the correct responses to all questions asked in a competitive examination. The Delhi Cantonment Board releases the key in two sequential stages:

• Provisional Answer Key: This is the initial solution sheet published immediately after the exam. It invites scrutiny from candidates. If candidates discover discrepancies, factual errors, or incorrect answer options, they are allowed to submit formal challenges backed by documentary evidence.
• Final Answer Key: After the objection submission window closes, a panel of subject matter experts reviews every submitted challenge. If an error is verified, the board updates the response key accordingly. The resulting final answer key is non-negotiable and forms the ultimate basis for calculating official test scores and declaring results.

How to Calculate Your Estimated Score

To compute your raw score accurately, you must apply the marking scheme designated in the recruitment notification. Typically, technical recruitments follow a standard scheme assigning positive marks for correct responses and deducting negative marks for incorrect entries.

Marking Scheme and Calculation Formula

Assume the examination awards 1 mark for every correct response and deducts 0.25 marks for every wrong answer. Unattempted questions carry zero penalties.

Raw Score = (Total Correct Answers × 1) - (Total Incorrect Answers × 0.25)

Section-Wise Analysis and Category-Wise Cut-Off Estimation

Candidates should dissect their performance section by section, separating core engineering topics from general aptitude or reasoning sections. This helps in understanding where marks were lost. While official cut-offs depend on multiple variables, comparing your raw scores against historical trends provides a realistic benchmark.

• Unreserved (UR): Generally requires a secure margin above 70 to 75 percent due to high competition.
• Other Backward Classes (OBC): Usually sits marginally below the unreserved threshold, around 65 to 70 percent.
• Scheduled Castes (SC) / Scheduled Tribes (ST): Cut-offs reflect reservation relaxations, commonly settling between 55 to 62 percent depending on test difficulty.
• Economically Weaker Sections (EWS): Competitiveness closely tracks the general or OBC brackets.

Complete Process to Raise an Objection

If you identify an error in the provisional answer key, you have the right to register a challenge through the official online interface. Offline applications or letters are not entertained under any circumstances.

Portal, Deadlines, and Fees

Objections must be filed within the stipulated window, usually lasting 7 to 10 days from the date of release. A non-refundable or conditionally refundable processing fee, typically 100 rupees per challenged question, must be paid through online payment gateways. Every objection must include clear, verifiable proof sourced from standard textbooks or academic publications. Vague references or internet forum screenshots are rejected immediately.

Outcomes of Objection Review

What Happens If Your Objection Is Accepted?

When the expert committee finds an objection valid, corrective action is taken across the board. If an answer option was wrong, the key is corrected, and marks are reallocated to candidates who marked the true correct answer. In cases where a question contains printing ambiguities or two correct options, full marks are either awarded to all candidates who attempted it or the question is completely annulled from the final evaluation. A revised key is published prior to result compilation.

What Happens If Your Objection Is Rejected?

If the committee determines that the original key is accurate, the challenge is dismissed and the provisional answer stands unchanged. The decision of the subject experts is final, and no direct appeals or personal hearings are granted. Candidates cannot file repetitive representations. While legal avenues or RTI applications exist, RTI cannot be used to force an evaluation change; it only provides access to existing evaluative records after the selection process concludes.

Judging Your Qualifying Chances Realistically

Avoid rushing to conclusions based solely on informal discussions or social media polls. Moderate your score expectations by accounting for potential human errors in your self-marking. If your calculated raw score lies comfortably above previous years' qualifying marks, begin preparing your technical portfolios and original documentation for the verification phase. If your score hovers near borderlines, stay neutral until the formal merit list appears.

Tips to Avoid Common Calculation Mistakes

• Double check question booklet paper codes to ensure you are consulting the matching answer key series (A, B, C, or D).
• Do not count questions marked for review as answered unless they were formally submitted before time expired.
• Carefully distinguish between unattempted questions and wrongly marked questions to avoid misapplying negative deductions.
• Always reference standard textbook solutions rather than personal interpretations when validating potential objections.
