  • Zones with higher applications (like Allahabad, Patna, Ajmer) usually have higher cutoffs.
  • Southern zones (Bangalore, Chennai, Thiruvananthapuram) and North-Eastern zones (Guwahati, Siliguri) generally see slightly lower cutoffs.
  • Reserved categories (SC/ST/OBC) get relaxation, and PwBD cutoffs are usually lower.

What Happens Next

  • After objections are processed, RRB will publish the final answer key.
  • Then they will declare the CBT-1 result, listing roll-numbers of those who qualify for CBT-2.
  • Candidates who clear CBT-1 will move to the next stages as per recruitment notification.

Key Takeaways

  • If you appeared for NTPC UG CBT-1, you can now download the answer key and estimate your marks.
  • Use the negative marking info properly to avoid over-estimating.
  • Keep an eye on cutoff estimates — if your score is near or above expected range, there’s a good chance to qualify.
  • Stay updated when the final answer key and results are published.

How to Calculate Normalized Score in RRB NTPC

Since RRB NTPC exams are held in multiple shifts, difficulty levels vary. To ensure fairness, RRB uses a Normalization Method to adjust raw marks.

Step 1: Raw Score

  • Correct answer = +1 mark
  • Wrong answer = -0.33 mark
  • Raw Score = (Correct × 1) – (Wrong × 0.33)

Step 2: Apply Normalization Formula

Formula:

Normalized Score = ((Your Score − Shift Mean) / Shift SD) × Common SD + Common Mean

Example

If your raw score = 55, shift mean = 50, shift SD = 10, common mean = 52, common SD = 12

Normalized Score = ((55 − 50)/10) × 12 + 52 = 58

⚡ Tip: If your shift was tough, normalization usually increases your marks.
