RRB Group D General Science Preparation Strategy
Follow below instructions for better performance in the RRB Group D General Science questions
1. Understand the Syllabus Clearly:
Focus mainly on Physics (basic laws and daily-life applications), Chemistry (everyday chemistry and simple reactions), and Biology (human body, plants, diseases, etc.).
2. Revise NCERT Books (Class 6–10):
Most questions are picked from basic NCERT science books. A quick revision of important topics like Human Body Systems, Laws of Motion, Acids-Bases, Electricity, and Environment is highly recommended.
3. Make Short Notes:
Prepare crisp notes for formulas, scientific phenomena, inventors, discoveries, and classification of plants and animals. Revise them regularly.
4. Practice MCQs Daily:
Solving previous years’ questions and important MCQs will build your speed and accuracy. Daily practice helps in memorizing facts easily.
5. Focus on Important Topics:
Topics like Human Physiology, Metals and Non-metals, Light, Sound, Diseases, Nutrition, and Force are highly important for the exam.
6. Take Mock Tests and Analyze:
Attempt mock tests specifically designed for RRB Group D. Analyze your weak areas and work on them.
