RPF SI Study Tips from Top Performers

1Prioritise General Awareness — at 50 of 120 questions it is the largest and most scoring section; build a daily current-affairs and static-GK habit including railway GK.
2Because of the -1/3 negative marking, attempt only questions you can answer with reasonable confidence and leave blind guesses unanswered.
3Drill arithmetic shortcuts for percentages, ratios, profit and loss, interest, and time-and-work so you can solve 35 questions quickly within the 90-minute limit.
4Practice reasoning patterns — coding-decoding, series, blood relations, direction sense, and syllogism — until they become near-automatic.
5Take full-length 120-question timed mocks under exam conditions, then review every wrong answer to fix recurring mistakes by section.
6Start PET fitness early: build up to the 1600 m (male) or 800 m (female) run timings and practise long jump and high jump well before the physical stage.
7Confirm your RRB region, admit-card download, ID requirements, and CBT centre logistics a few days before the exam.
