FAQs
The ideal source for RRB Group D Science Notes is NCERT Class 9 and 10 Science textbooks, as the majority of questions are directly based on these concepts. Candidates should complement NCERT with exam-focused notes, previous year questions, and regular MCQ practice to understand how concepts are framed in the exam.
On average, 30–45 minutes daily is sufficient for Science preparation if done consistently. This time should include concept revision, short notes review, and solving 15–20 MCQs.
Among Physics, Chemistry, and Biology, Biology carries the highest weightage in the RRB Group D exam. Topics like human physiology, diseases, nutrition, and environment are frequently asked. Hence, Biology should be given slightly more priority while preparing RRB Group D Science Notes.
Yes, previous year questions (PYQs) are extremely important. Many Science questions in RRB Group D exams are either repeated or asked with minor modifications. Solving PYQs helps candidates identify high-frequency topics, avoid common traps, and improve accuracy.
Basic memorisation is required, especially for units, diseases, chemical formulas, and biological terms, but it should be supported by conceptual understanding.
