Effective Study Plan (3045 Days)

Day 15: Foundation

• Collect standard GIR books (e.g., R.S. Aggarwal, Arihants Reasoning).
• Read theory for each topic; create onepage summary notes.
• Identify personal weak areas.

Day 620: Practice Core Topics

• Allocate 23 days per major subtopic.
• Solve 2030 problems daily, focusing on accuracy first.
• Review solutions immediately; note recurring patterns.
• Use flashcards for analogies and series rules.

Day 2130: Mixed Sets & Timed Sessions

• Take 2hour mock sets that mix verbal and nonverbal questions.
• Aim for completing 4045 questions per hour.
• Analyse each mock: mark attempted, unattempted, and wrong answers.
• Rework every mistake with explanation.

Day 3138: Strengthening Speed

• Introduce speed drills solve 10 questions in 2 minutes.
• Practice shortcut techniques (e.g., using difference of squares for series).
• Use online timers or mobile apps for realistic exam simulation.

Day 3945: FullLength Mock Exams

• Attempt 34 complete RRB Group D mock papers under strict timing.
• Target a minimum score of 70% in GIR.
• Final review of all error logs and summary notes.

Top ShortCut Strategies

• Number Series Look for common differences, ratios, alternating patterns, or a combination of both.
• Direction Problems Visualise a miniature compass; write down L, R, S, B repeatedly to avoid confusion.
• CodingDecoding Identify if the code is based on position shift, reverse alphabet, or numeric substitution.
• Clock Problems Convert hourhand and minutehand movement into degrees (30 per hour, 6 per minute).
• Blood Relations Start from the reference person, assign generation numbers (positive for ancestors, negative for descendants) and calculate.
• Paper Cutting & Folding Sketch quickly; fold lines simplify the visualisation.

Common Mistakes to Avoid

• Skipping easy questions to start with tough ones leads to time shortage.
• Relying only on memorisation without understanding the underlying pattern.
• Ignoring the negative marking (if applicable) and guessing blindly.
• Not reviewing errors; repeating the same mistakes in subsequent mocks.
• Studying for long hours without breaks reduces concentration.

Final Checklist Before the Exam Day

• Complete at least three fulllength mock tests.
• Review summary notes and shortcut formulas.
• Check the admit card, ID proof, and exam centre address.
• Plan a healthy sleep schedule aim for 78 hours.
• Carry a bottle of water, a stationary set, and a watch (if allowed).

With systematic preparation, consistent practice, and the right strategies, you can convert the General Intelligence & Reasoning section from a challenge into a confidencebuilder. Best wishes for a successful Railway Group D journey!
