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.
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.
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.
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.
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.
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.

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.
