RRB NTPC 2026: Step-by-Step Guide to Calculate Your Graduate Level Exam Marks Using the Answer Key

The Railway Recruitment Board (RRB) has officially released the RRB NTPC Graduate Level Answer Key 2026 on April 6, 2026, at 4:00 PM. This crucial step comes after the Computer Based Test (CBT-1) conducted between March 16 and March 27, 2026, allowing over 40 lakh candidates to cross-check their responses. Calculating your raw score using the answer key can give you an early estimate of your performance and help you anticipate eligibility for CBT-2 before the official results.

Important Dates for RRB NTPC Answer Key 2026

Before calculating your marks, it’s important to be aware of the timeline for answer key downloads and objections:

RRB NTPC 2026 Marking Scheme (CBT-1)

Understanding the marking scheme is the first step to calculating your raw score accurately.

• Total Questions: 100
• Marks per Correct Answer: +1
• Negative Marking: -1/3 (0.33) per incorrect answer
• Unattempted Questions: 0 (No penalty)

The CBT-1 exam duration is 90 minutes for Graduate Level posts.

Step-by-Step Guide to Calculate Your Marks Using the Answer Key 2026

Follow these steps once you download your response sheet from the official RRB portal (rrbcdg.gov.in):

1. Count Correct and Incorrect Responses

Compare your responses with the official answer key:

• Correct (C): Answers that match the official key
• Incorrect (I): Answers that do not match

2. Apply Negative Marking Formula

RRB applies negative marking strictly. One mark is deducted for every three incorrect answers.

Formula:

$Total\; Score=(Number\; of\; Correct\; Answers)-(Number\; of\; Incorrect\; Answers\times 1/3)$

3. Example Calculation

If you attempted 85 questions, with 70 correct and 15 incorrect answers:

• Positive Marks: 70 × 1 = 70
• Negative Marks: 15 × 1/3 = 5
• Final Raw Score: 70 − 5 = 65

Understanding Normalization and Percentile Scores

Since the RRB NTPC CBT-1 was conducted in multiple shifts, the raw score alone does not determine your final ranking.

• Normalization Method: Balances difficulty levels across different shifts
• Percentile Score: Shows how many candidates scored less than or equal to you in your shift
• Final Merit List: CBT-2 shortlisting is based on Normalized Marks, not raw scores

How to Raise Objections Against the Answer Key

If you notice any discrepancies in the official answer key—such as wrong answers or ambiguous questions—follow these steps:

1. Log in to your regional RRB portal using your Registration Number and Date of Birth
2. Click on the “Objection Tracker” link
3. Select the Question ID you want to challenge
4. Upload supporting evidence
5. Pay a fee of ₹50 per question via online mode (refundable if objection is valid)
