What Is Normalization In RRB NTPC Exam?
Normalization means to measure the different values of different times on the same scale. The normalization process followed by RRBs is a scientific and statistical process. It is not a process of awarding grace marks. The normalized score completely depends on the statistical parameters calculated based on the performance of candidates attending the exam in the different sessions. The normalization procedure is going to be totally supported by the raw score of candidates. The raw score is evaluated based on the number of questions attempted correctly or wrongly. These are the scores that are obtained by the aspirants by answering correctly in each section of the Exam. These are the scores calculated after applying the penalty for wrong answers.
Why normalization is necessary?
When an examination is conducted in multiple sessions for the same syllabus, in spite of all efforts there are chances of variation in the difficulty level of the questions in various sessions. Thus the score obtained by the candidates of the same caliber is likely to vary. In order to equalize the variation in the difficulty level of question papers a process called statistical normalization of marks is resorted to universally. This ensures a level playing field for all the candidates.
RRB NTPC Normalization Marks Revised Formula
Railways have released a revised formula for the calculation of normalized marks for multi-session papers has been published. The formula has been modified as mentioned below and will be adopted for normalization:-
What is Raw Score? How Raw Score is calculated?

The Raw Score is computed as under:
Total Questions-100; No of Questions Ignored (question wrong, multiple options correct etc): 2
No of Questions attempted: 60; Correctly Answered: 54; Wrongly Answered: 6
Positive Marks: 54; Negative Marks: 2; Net Score: 54-2=52
Score Out of 100: (52/98)*100= 53.06
