1. Railway Recruitment Exam Architecture (CBT 1 & CBT 2)
Railway examinations test speed, negative marking discipline (1/3rd deduction), and high-frequency General Science / Awareness recall:
100 Questions • 90 Minutes
- General Awareness (History, Geography, Science, Current Affairs): 40 Questions
- Mathematics (Arithmetic, Algebra, Trigonometry): 30 Questions
- General Intelligence & Reasoning: 30 Questions
- Negative Marking: 1/3rd mark penalty for each wrong answer.
120 Questions • 90 Minutes
- General Awareness: 50 Questions (Highest Weightage)
- Mathematics: 35 Questions
- General Intelligence & Reasoning: 35 Questions
- Followed by Computer-Based Aptitude Test (CBAT) or Typing Skill Test.
2. High-Yield General Science Breakdown (NCERT Class 9-10)
In RRB examinations (especially Group D and ALP), General Science accounts for 25 to 30 direct questions. Key high-frequency themes include:
Physics
Newton's Laws of Motion, Work, Energy & Power formulas, Gravitation, Sound waves (Doppler effect, ultrasonic frequencies), Light (Mirror and Lens formulas, total internal reflection), and Ohm's Law electrical circuits.
Chemistry
Mendeleev vs Modern Periodic Table trends, chemical reactions (redox, combination, displacement), Acids, Bases & Salts (pH values of common substances), Metals and Non-metals extraction, and Carbon compounds.
Life Sciences (Biology)
Cell organelles (mitochondria, ribosomes), human organ systems (circulatory system, blood groups, nervous system), vitamins and deficiency diseases, plant photosynthesis, and infectious pathogens.
