IAF Group C study plan

IAF Group C · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

General Intelligence and Reasoning & Numerical Aptitude / Quantitative Ability

  • Map the full General Intelligence and Reasoning syllabus into a one-page checklist covering analogies, series (number, letter, mixed), coding-decoding, blood relations, directions, syllogisms, seating arrangement, ranking, clocks and calendars, and non-verbal reasoning.

  • Drill 60 number-series and letter-series questions across easy-to-moderate difficulty and log every wrong answer with the pattern rule you missed.

  • Solve 40 analogy and classification questions under a 45-second-per-question timer to build speed on the highest-frequency scoring items.

  • Complete a 30-question mixed reasoning sectional test and record accuracy by question type to identify your two weakest subtypes.

  • Refresh core arithmetic (percentages, ratio, averages) with 25 practice sums to prepare for calculation-heavy reasoning and quant questions.

Your checkpoint

A reasoning error log with at least 40 categorized mistakes plus a baseline sectional score sheet showing accuracy per question type.

Week 2

General Intelligence and Reasoning & Numerical Aptitude / Quantitative Ability

  • Master seating arrangement and puzzle sets by solving 15 two-row and circular arrangements, drawing every arrangement before answering.

  • Work through 40 syllogism and logical-deduction questions using Venn diagrams, and state the rule that eliminates each wrong option.

  • Solve 50 quantitative questions on time-speed-distance, trains, and boats-and-streams, applying the standard formula sheet you build this week.

  • Complete 30 non-verbal reasoning items (mirror images, paper folding, embedded figures, figure series) and note which figure types cost you the most time.

  • Take a 40-question combined reasoning-plus-quant sectional timed at 40 minutes and review every skipped question.

Your checkpoint

A one-page formula and rule sheet (arithmetic + logical rules) plus a timed sectional score with per-question time averages.

Week 3

Numerical Aptitude / Quantitative Ability & General Intelligence and Reasoning

  • Solve 60 problems on profit and loss, simple and compound interest, and discount, including at least 15 multi-step word problems.

  • Complete 50 questions on mensuration and geometry covering triangles, circles, rectangles, cylinders, and cones, memorizing each area and volume formula as you go.

  • Practice 40 coding-decoding, blood-relation, and direction-sense questions to raise accuracy on these high-yield reasoning types above 80 percent.

  • Build a personal quant shortcut card listing 10 calculation tricks (squares to 30, fraction-to-percent conversions, approximation) and verify each on 5 sums.

  • Take a 50-question quantitative aptitude sectional in 45 minutes and record your accuracy and attempt rate.

Your checkpoint

A shortcut card with 10 verified calculation tricks and a 50-question quant sectional score report.

Week 4

General Awareness and General Knowledge & General English

  • Compile a dated current-affairs digest covering the last six months across national events, appointments, schemes, sports, awards, and defence and railway developments relevant to Group C recruitment.

  • Revise static general knowledge by topic (Indian polity, geography, history, economy, and general science) and write 150 one-line facts from memory.

  • Learn and apply 60 English grammar rules covering subject-verb agreement, tenses, articles, prepositions, and common confusions, completing 100 fill-in-the-blank items.

  • Practice 40 sentence-correction and error-spotting questions and classify each error by grammar rule.

  • Attempt 30 synonym, antonym, and one-word-substitution items and start a vocabulary notebook limited to words you actually got wrong.

Your checkpoint

A six-month current-affairs digest plus a 150-fact static GK recall sheet, both self-tested with a 50-question GK quiz scoring at least 60 percent.

Week 5

General Intelligence and Reasoning & General English

  • Complete 20 full reasoning puzzle sets (floor-based, scheduling, comparison) within a strict 8-minute-per-set limit.

  • Solve 60 English questions on reading comprehension, cloze test, and para-jumbles, underlining the textual clue for each answer.

  • Revise the entire reasoning error log from weeks 1 to 3 and re-solve every logged mistake until each is correct without hints.

  • Practice 40 idiom, phrase-replacement, and active-passive/voice questions to cover the remaining high-frequency English types.

  • Take a 50-question combined reasoning and English sectional in 45 minutes and compare accuracy against your week 3 baseline.

Your checkpoint

A completed error-log re-solve sheet showing at least 90 percent of previously wrong reasoning and English items now answered correctly.

Week 6

General Intelligence and Reasoning & Numerical Aptitude / Quantitative Ability & General Awareness and General Knowledge

  • Attempt two full-length mock tests simulating exam timing and section order, and log raw scores, accuracy, and attempts per section.

  • Analyze each mock within 48 hours, tagging every error as knowledge gap, silly mistake, or time pressure, and list the top five fixes.

  • Re-drill 60 quantitative questions drawn only from your weakest three quant topics identified in the mock analysis.

  • Re-drill 40 reasoning questions from your two weakest reasoning types, using timed sets of 10.

  • Update the current-affairs digest with the latest month and quiz yourself on 50 new GK facts.

Your checkpoint

Two completed full-length mock scorecards with a written error-tagging analysis and a prioritized list of five corrective actions.

Week 7

Trade / Post-Specific Technical Knowledge & Basics of Computer Knowledge and Office Procedures

  • Study the trade or post-specific technical syllabus for your chosen Group C post and write a 100-point summary of its core concepts, terminology, and safety or procedural rules.

  • Solve or self-test 50 technical-knowledge questions from your summarized notes and mark any fact you cannot verify confidently for further checking.

  • Learn computer fundamentals: hardware and software basics, input and output devices, memory types, file management, and basic troubleshooting, tested with 30 questions.

  • Practice office procedures and standard software tasks: word-processing formatting, spreadsheet formulas and basic functions, email etiquette, and file and record handling, demonstrated on 10 hands-on exercises.

  • Take a 40-question mixed technical-plus-computer sectional and record accuracy separately for each domain.

Your checkpoint

A 100-point technical summary sheet, a completed 10-exercise computer and office-procedures worksheet, and a sectional accuracy report.

Week 8

General Intelligence and Reasoning & Numerical Aptitude / Quantitative Ability & General English & General Awareness and General Knowledge

  • Take three full-length mock tests in the final ten days, each followed by a same-day review of every incorrect and guessed answer.

  • Re-revise the formula sheet, shortcut card, grammar rules, current-affairs digest, and technical summary in four rotating 90-minute revision blocks.

  • Re-solve the 50 highest-risk items from your cumulative error log to confirm retention.

  • Finalize an exam-day time-allocation plan per section and rehearse it in the last mock, including a defined cutoff time for abandoning any question.

  • Confirm logistics: admit card, ID, exam-centre route, and a light revision-only plan for the final 48 hours.

Your checkpoint

A final mock scorecard at or above your target, a one-page exam-day time plan, and a fully re-solved high-risk error list.

Milestones

Week 2: Reasoning sectional accuracy reaches at least 65 percent with average time under 50 seconds per question, and the error log contains 60 or more categorized entries.

Week 4: Quant sectional accuracy reaches at least 65 percent, the static GK self-quiz scores at least 60 percent, and the grammar rule set is complete and self-tested.

Week 6: Both full-length mocks are completed within time, overall score improves between mock one and mock two, and every error is tagged with a corrective action.

Week 8: Final mock score meets or exceeds the target, all five revision assets are re-read, and 90 percent or more of high-risk logged errors are re-solved correctly.
