A complete, honest guide to preparing for Common Admission Test: a real self-study path, a weekly study plan, how tough it actually is, and what the job pays. Everything you need is free on Shishya — no coaching fees.
CAT is one of the few exams where self-study genuinely works if you're disciplined. Lakhs clear it every year without spending a rupee on coaching. Here's your roadmap:
Foundation building (Months 1–3)
Quant: Start with NCERT Maths (Class 6–10) if your basics are weak. Then move to Arun Sharma's "How to Prepare for Quantitative Aptitude" — this is the Bible. Cover arithmetic, algebra, geometry, modern maths, and number systems chapter by chapter.
VARC: Read daily. The Hindu editorials, Economic Times opinion pieces, anything well-written. Download the app "A Word A Day" for vocabulary. For grammar, Wren & Martin basics are enough. Practice RC passages from free sources like Project Gutenberg.
DILR: Start with Arun Sharma's LR book. Begin with easy sets (blood relations, seating arrangements, Venn diagrams). DILR is pure practice; theory won't help much.
Practice phase (Months 4–7)
Download previous year CAT papers (2015 onwards) from official IIM sites or Shishya's PYQ section — these are gold.
Take Shishya's free mocks religiously. CAT is as much about time management and dealing with pressure as it is about solving questions. One full mock per week minimum, analyse it for two days. Track which question types eat your time.
Create an error log: note every mistake, categorize it (silly error, concept gap, time pressure), and revisit weekly.
Join free Telegram groups where aspirants share shortcuts, but don't get lost in "1000 tricks" PDFs — master the basics first.
Final stretch (Months 8–10)
Shift to 2–3 mocks per week. Shishya's free platform covers this entirely; you don't need paid mocks unless you want variety.
Solve sectional tests to build stamina in weak areas.
Revise formulas daily: maintain a one-page cheat sheet for quant (quadratic formulas, geometry theorems, time-work-distance basics).
For VARC, attempt 4–5 RC passages daily. Speed matters: aim for 5–6 minutes per passage initially, then bring it down to 4.
Free resources checklist
Shishya's free mocks, PYQs, and notes (your core prep material)
Unacademy/YouTube free CAT lectures (Rodha's quant videos are excellent)
GradeUp/Oliveboard free daily quizzes
Pagalguy forums for doubt-clearing and strategy discussions
With coaching
If you can afford it or your parents insist, coaching can provide structure and peer pressure. Top options:
TIME, IMS, CL: ₹30,000–50,000 for classroom programmes. Good if you need hand-holding and a fixed schedule.
Unacademy Plus, 2IIM online: ₹10,000–20,000. Flexible, video-based, useful if you're working or in final-year college.
But here's the truth: Coaching doesn't teach you anything you can't learn yourself. They use the same Arun Sharma books, give mocks (which Shishya provides free), and their "shortcuts" are available on YouTube. Coaching's only edge is discipline and doubt-clearing. If you're self-motivated, save that ₹40,000 for your MBA application fees instead.

Study plan
This is a 40-week plan (10 months), assuming you're starting from scratch. Adjust based on your current level and college/job commitments.
Months 1–3: Foundation (25 hrs/week)
*Weekly structure:*
Monday–Tuesday (5 hrs): Quant theory. One chapter from Arun Sharma (e.g., Percentages), solve all Level-1 and Level-2 questions.
Wednesday (4 hrs): DILR sets. Attempt 6 sets (mix of easy, moderate, tough). Spend 10 minutes per set max.
Thursday (4 hrs): Weak area focused study. If quant geometry is weak, do only geometry today.
Friday (3 hrs): Light practice, revision. Go through your error log, redo mistakes from the week.
Saturday (4 hrs): Full CAT mock (2 hrs) + quick analysis (2 hrs). Use Shishya's free mocks. Note cutoff sections, accuracy, time per question.
Sunday (7 hrs): Deep mock analysis. Review every single question — even the ones you got right. Identify patterns: Are you always running out of time in DILR? Is your VARC accuracy dropping below 70%? Plan next week based on this.
Target by Month 7: Completing mocks with 70–75% accuracy, finishing each section within time, percentile in practice mocks crossing 85.
---
Months 8–10: Final sprint (35–40 hrs/week)
*Weekly structure:*
Monday–Tuesday (8 hrs): Two sectional tests. One VARC (40 mins), one Quant (40 mins) on Monday. One DILR (40 mins) + revision on Tuesday.
Wednesday (4 hrs): Solve PYQs you haven't attempted yet. CAT changes patterns slightly every year, but concepts repeat.
Thursday–Friday (8 hrs): Two full mocks. Shishya + one other free platform (like Cracku or MBA Rendezvous free mocks).
Saturday (6 hrs): Mock analysis day. Compare performance across mocks. Are you improving in weak areas?
Sleep 7–8 hours. A tired brain fails in DILR, guaranteed.

Is it tough? An honest take for an average student
Let's not sugarcoat it: CAT is tough, but not because of difficulty — because of competition and time pressure.
The math reality About 2.5–3 lakh students appear for CAT every year. The top IIMs (A, B, C) call roughly the top 1–2% for interviews. That's a 98+ percentile requirement. Even good newer IIMs need 90+ percentile. So yes, the bar is high.
But here's what "average student" actually means:
If you scored 60–70% in Class 10 Maths and can handle basic English, you're not average — you're capable. CAT doesn't test brilliance; it tests speed, accuracy, and temperament.
I've seen engineering students with 8.5 CGPAs struggle because they overthink, while a BA student who practiced religiously crosses 95%ile. Your Board marks don't predict CAT success.
What makes it tough 1. Time crunch: 40 minutes per section, roughly 22–26 questions each. You get ~90 seconds per question in Quant and VARC, maybe 10 minutes per DILR set. One slow section and you're scrambling. 2. Negative marking: –1 for every wrong MCQ (out of +3). If your accuracy drops below 65–70%, you're actually losing marks. 3. Unpredictable DILR: Some years, DILR sets are straightforward. Some years (like CAT 2023), they're nightmarishly hard. You can't predict it, which messes with confidence. 4. Reading Comprehension endurance: 4–5 dense, boring passages (economics, sociology, abstract philosophy). If you hate reading, VARC will torture you.
Can an average student crack it? Absolutely, but you need 8–10 months of focused prep. Not "I'll study when I feel like it" — actual structure. If you can give 25–30 hours a week consistently, solve 50+ questions daily, take weekly mocks, and learn from every mistake, you'll comfortably hit 85–90 percentile. For 95+, you need 35–40 hours/week and near-perfect accuracy.
The mental game CAT punishes panic. You'll encounter 1–2 questions you've never seen before. Accept it, move on, come back later. Students waste 5 minutes on an unsolvable DILR set, then rush through easy quant — that's how averages stay average. The toppers aren't necessarily smarter; they're calmer and better at choosing which questions to skip.
Bottom line: If you're reading this guide, willing to put in the hours, and can handle delayed gratification (10 months is a long grind), you're already above average in discipline. CAT rewards consistency more than genius.

Salary, job profile & career growth
Post-MBA salary (not CAT itself — CAT is just the entrance exam):
MBA from top IIMs (A, B, C, L, I, K): Average domestic placements approximately ₹25–35 lakh per annum; top international offers can go ₹50 lakh+. You land roles in consulting (McKinsey, BCG, Bain), investment banking (Goldman Sachs, Morgan Stanley), product management (Google, Amazon, Flipkart), or leadership programmes in FMCG/pharma giants like HUL, P&G, ITC.
Tier-2 IIMs and top private B-schools (FMS, XLRI, SPJIMR, MDI, IIFT): Approximately ₹15–22 lakh average. Roles in sales/marketing management, business analytics, operations, finance, HR leadership.
Newer IIMs and good private colleges: Approximately ₹8–15 lakh. Still solid ROI if fees are under ₹10 lakh.
Career growth: Post-MBA roles typically start at Assistant Manager/Management Trainee. By Year 3–5, you're a Manager; by Year 7–10, Senior Manager/Associate Director. Consulting and finance offer fastest growth. Entrepreneurship is common; many MBA grads launch startups after gaining 3–5 years of experience. The network and brand value of a good B-school compound over decades.

Frequently asked questions
Q. Can I crack CAT while working full-time or in final-year engineering?
A. Yes, thousands do it every year. You'll need 2–3 hours daily without fail — early mornings or late nights. Take mocks on weekends. Avoid binge-studying; consistency beats cramming. Use commute time for reading editorials or revising formulas on your phone.
Q. Which section should I focus on if I'm weak in all three?
A. Start with Quant — it's formulaic and improves fastest with practice. A strong Quant score compensates for weaker VARC/DILR in many IIMs' sectional cutoffs. But don't ignore DILR entirely; even 50–60% accuracy there keeps you in the race. VARC needs daily reading habit.
Q. How many mocks should I take before the actual CAT exam?
A. Minimum 25–30 full-length mocks over 5–6 months. One mock per week initially, then 2–3 per week in the final two months. Shishya's free mocks are enough; don't hoard 100 mocks. Quality of analysis matters more than quantity of attempts.
Q. Do IIMs only consider CAT score, or do Class 10/12/graduation marks matter?
A. Both matter. CAT score (percentile) gets you the interview call, but overall selection includes academics, work experience, gender diversity, and interview performance. Old IIMs weight past academics heavily; newer IIMs focus more on CAT percentile. Check each IIM's selection criteria on their websites.
Q. Is attempting all questions necessary, or should I focus on accuracy?
A. Accuracy over attempts, always. Due to negative marking, attempting 20 questions with 85% accuracy (17 correct, 3 wrong = 51–3 = 48 marks) beats attempting 30 with 60% accuracy (18 correct, 12 wrong = 54–12 = 42 marks). Skip confidently and strategically.
