Key Focus: Science Preparation for RRB NTPC CBT 2

Although science is not a standalone section in the CBT exams, it is a significant part of the General Awareness section. Here’s a strategic approach to prepare effectively:

A) Identify the Syllabus and Important Topics

Science questions in the General Awareness section typically cover topics from:

  • Physics: Laws of motion, force, work, energy, power, units and measurements, sound, light, heat, and thermodynamics.
  • Chemistry: Chemical reactions, acids and bases, the periodic table, metals and non-metals, atomic structure, and environmental chemistry.
  • Biology: Human body systems, plants and animals, diseases, nutrition, genetics, and ecology.
  • Environmental Science: Pollution, climate change, conservation of natural resources, and sustainable development.

B) Use Reliable Study Materials

Choose standard textbooks and reference books to cover the fundamentals. NCERT books from classes 6 to 10 are highly recommended for concise and clear explanations. Additionally, RRB-specific guidebooks can provide targeted practice questions and previous years’ papers.

C) Practice with Mock Tests and Previous Papers

Engaging with mock tests and previous year question papers helps you grasp the exam pattern and enhances your time management skills.
