Railways | RRB Paramedical Staff
RRB Paramedical Staff sets 10 General Science questions for 10 marks in the Computer Based Test, so it is worth planning your preparation around the topics below.
Physics, chemistry and biology at roughly the secondary-school level, tested as direct factual recall. NCERT-level fundamentals cover most of it, and the questions repeat across cycles, so past-paper topics are the sharpest guide to what to revise.
