Most RRB Group D aspirants treat Chemistry as an afterthought — and lose 3–5 easy marks because of it. The Science section carries 25 marks in the CBT, and Chemistry alone accounts for roughly 7–8 questions based on previous year papers.
The good news? RRB Group D Chemistry stays strictly at Class 9–10 NCERT level. No advanced concepts, no derivations. With the right strategy, scoring full marks here is genuinely achievable.
🎯 Quick Answer (30-Second Read)
- Chemistry contributes approximately 7–8 marks out of 25 in the RRB Group D Science section
- High-yield topics: Acids/Bases/Salts, Metals & Non-metals, Carbon compounds, Periodic Table, Chemical Reactions
- NCERT Class 9 and 10 Chemistry chapters are sufficient — no additional books needed
- Students who solve 50+ previous year Chemistry MCQs score significantly higher than those who only read theory
- Revision over 3–4 cycles beats reading new material in the final week

Identify the High-Yield Topics First
Not all Chemistry topics carry equal weight in the exam. Spending equal time on every chapter is the biggest mistake aspirants make.
Based on previous RRB Group D papers, these topics appear most frequently:
— pH scale, indicators, neutralisation reactions
— reactivity series, properties, extraction
— functional groups, homologous series, IUPAC basics
— types of reactions, balancing equations
— trends in properties, groups and periods
Amit from Lucknow, who scored 88/100 in RRB Group D CBT 2022, focused exclusively on these five topics for Chemistry: "I didn't touch anything outside NCERT. Three revision cycles of these chapters gave me 7 out of 8 Chemistry questions."
The Right Revision Method for Chemistry
Reading theory once is not enough. Active recall beats passive reading — this is why most students who "study" Chemistry still get questions wrong.
Follow this three-step method:
Read the NCERT chapter once for concepts (Day 1)
Solve 15–20 MCQs from that chapter immediately after (Day 1–2)
Revise only your wrong answers and weak areas (Day 4–5)
In our analysis of 400+ PrepGrind Group D students, those who completed at least three revision cycles on Chemistry scored an average of 6.8/8 marks — versus 4.2/8 for those who revised only once.
What to Memorise vs. What to Understand
Some Chemistry content requires pure memorisation; other parts need conceptual clarity.
Memorise
- • Reactivity series of metals
- • pH values of common substances
- • Names of functional groups
- • Types of chemical reactions
Understand
- • Why metals above hydrogen displace it
- • How pH affects indicators
- • How carbon forms different compounds
- • How to identify reaction type from equation

Your Final-Week Action Plan
The week before the exam, stop reading new material entirely. Focus only on:
- Solving 2 full-length mock tests daily and reviewing Chemistry questions specifically
- Revising your error log — the questions you got wrong during practice
- Quickly reviewing the memorisation list (reactivity series, pH values, functional groups)
Sneha from Nagpur revised her Chemistry error log every morning for the last five days before her exam and improved her mock test Chemistry score from 5/8 to 8/8. The pattern was simple: she was making the same mistakes repeatedly — revision fixed them.
