Why Estimated Marks May Differ from Final Marks

The marks you calculate from the RRB NTPC UG tentative answer key 2025 may change due to normalization and objections.

• Objection Process: If RRB accepts valid objections, some answers may change.

• Normalization of Marks: Since the exam is held in multiple shifts, RRB applies a normalization formula to balance difficulty levels across sessions.

• Dropped Questions: If any questions are cancelled, marks may be adjusted accordingly.

Key Points for Candidates

• The RRB NTPC UG answer key 2025 helps only in self-assessment, not final results.

• Do not treat tentative marks as your final score.

• Final scores will be calculated after applying the normalization formula.

• Candidates should raise objections (if any) within the official time frame.

Final marks will be declared in the RRB NTPC UG Result 2025.
