Subject-Wise Deep Dive for Railway Aspirants
1. General Science (The Make-or-Break Section)
Unlike other SSC or Banking exams, RRB asks conceptual and direct numerical questions from Class 9th and 10th NCERT books:
- Physics: Focus on Motion equations ($v = u + at$), Work-Energy-Power, Ohm’s Law ($V = IR$), Lens & Mirror formulas.
- Chemistry: Master Modern Periodic Table trends (Groups, Periods), Chemical Reactions, and Common Chemical Names (e.g., Washing Soda, Bleaching Powder).
- Biology: Human Systems (Digestive, Circulatory, Respiratory), Plant Anatomy, and Vitamin deficiency diseases.
2. Mathematics & Speed Tricks
Railway math questions are straightforward but time-bound. Master quick calculations for fractions, LCM-HCF, Simplification, Pipe & Cisterns, and Speed-Distance-Time.
