Normalization shift variations depend on average shift difficulty scores across all exam days.
Category-wise cutoffs (UR, OBC, EWS, SC, ST) vary each year based on vacancies and candidate count.
Railway Normalization Process
Indian Railways uses percentile-based or standard deviation normalization across multiple examination sessions.
Why do marks increase or decrease after RRB normalization?
If your shift average was lower than the base shift, your marks increase to balance the harder test paper.
