Understanding the Weightage of Science in RRB
In Railway Recruitment Board exams, General Science is a decisive scoring pillar. Unlike broad General Studies, Science questions in RRB are objective, fact-based, and rarely open to ambiguity.
A systematic 4-week review of Class 9 and 10 NCERT concepts guarantees near-perfect accuracy.
Core Physics & Chemistry Formula Handlist
Railway exams frequently test basic one-step numerical calculations. Familiarize yourself with standard dimensional formulas, SI units, and universal constants.
- Physics: v = u + at, s = ut + 0.5at², v² = u² + 2as, V = IR, P = V²/R = I²R.
- Chemistry: Balancing redox reactions, pH scale calculations, properties of noble gases, and ore extraction metallurgy.
- Biology: Human digestive enzymes, plant tissue classification (Xylem/Phloem), hormone functions, and deficiency diseases.
