RRB Group D: General Science

  • Major Topics: Physics [Heat, Light, Sound, Electricity, Magnetism, Forces in Nature, Earth’s rotation and Revolution, Gravitation, etc.]; Chemistry [Matter, Elements & compounds, Application-based chemistry, Fuels, Polymer, Nuclear energy, nuclear reactors in Indian, etc.]; Biology [Cell, Plant Kingdom, Animal Kingdom, major Diseases, Inheritance, Genes; Evolution of Earth; Astronomy; Current Affairs, etc.
  • The 25 questions on the General Science section consists of Physics, Chemistry and Biology. The level of questions typically stands at class 10th As per last year, Chemistry accounted for the highest weightage with 9-10 questions with Physics next carrying about 7-8 questions and lastly Biology having 6-7 questions.
  • General Science is best studied through the NCERT books 7th-10th and at times of 11th and 12th. Keep a Lucent’s GK book handy for reference on static topics such as dates, inventors and major discoveries. Keep an eye on the Science and Tech page on dailies as well.

How to Prepare for RRB Group D: Mathematics

  • Major Topics: Ratio & Proportion, Number System, Speed & Distance, Simplification/ Approximation, Percentages, Profit & Loss, Average, Inequalities, Trigonometry, Probability, Simple & Compound Interest, Ages, Functions, Geometry, Linear & Quadratic Equations, Series & Sequences, Permutation & Combination, Probability, Data Interpretation, etc.
  • Going by the last year paper, time & work carried the highest weightage with 3-4 questions with ratio & proportion, percentages, BODMAS, Time & Distance, Age, etc. also accounting for 2-3 questions each.


  • Having a solid arithmetical base lead to efficiency in reasoning ability as well. Thus, cement your fundamental mathematics portion in the first phase of your RRB Group D study plan itself. Move on to advanced topic like Trigonometry, Quadratic Equations and Probability in the next phase.


How to Prepare for RRB Group D: General Intelligence and Reasoning

  • Important Topics: Cause & Effect, Assertion & Reason, Statements & Conclusion Inequalities, Partnership, Blood Relation, Coding-Decoding, Clocks, Puzzles, Seating Arrangement, Dates & Calendars, Order & Rankings, Directions, Data Sufficiency, Similarities, Relationships, Advanced Coding-Decoding, Advanced Puzzles, Syllogism, etc.
  • The 30 questions on the General Intelligence & Reasoning section included in the previous year paper, 4-5 questions on Statements along with 3-4 questions each on Analytical Reasoning and Alphabetical & Number series. Coding & decoding and Analogies were also asked in total 5-6 questions.
  • Utilise creative learning techniques such as flow charts, diagrams, puzzles and quizzes to acclimatize yourself with the diverse types of questions asked in this section. Take 1-2 short topic-based tests to assess yourself continuously in your RRB Group D study plan.

RRB Group D preparation plan: Key Takeaways

  • Time Management: 90 minutes is a bit of a stretch for 100 questions. Therefore, it is important to start confidently and from familiar sections. If you accord 54 seconds per question, you will be on point but Reasoning and Mathematics sections tend to take more time than expected. So, don’t linger on one question too much and plan accordingly. Stress on time management in your RRB Group D study plan.
  • Starting Tactic: As mentioned above, to start well gives you some breathing room. Our suggestion is, to begin with, either of Reasoning and Mathematics sections. Then, complete General Science and move on to the remaining one of the above two. Leave General awareness for the end. Try out multiple starting approaches in your RRB Group D preparation plan.
  • Revision: Almost as crucial is the revision part. Even if you are short on time, always leave 5-7 minutes in the end. Or else you can revise for 2-3 minutes after completing two sections as well. Look out for calculation errors, marking mistakes and other silly slip-ups you may have committed.


The most important part of your RRB Group D study plan is your confidence and trust in your abilities. have faith in your exam strategies, remain patient and don’t give in to nervousness. Best of luck.
