The Golden Rule — Samacheer Kalvi First
Before buying a single coaching guide or joining a test series, do this one thing: download the Samacheer Kalvi textbooks for free.
Go to tnschools.gov.in — the official Tamil Nadu government portal — and download every Samacheer Kalvi book from Class 6 to Class 12. All books are available as free PDFs. There is no reason to pay for them.
Why Samacheer Kalvi is non-negotiable:
60–70% of TNPSC questions in every group — from Group 4 to Group 1 — are drawn directly from Tamil Nadu State Board textbooks. TNPSC examiners write questions from these books. If you haven't read a chapter in Samacheer Kalvi Social Science or Science, you cannot answer questions from it — no matter how many coaching guides you have read.
The most common mistake Tamil Nadu TNPSC aspirants make is this: they buy Sura's guides, join a coaching centre, watch YouTube shortcuts — and never properly read Samacheer Kalvi Class 10 History or Class 9 Geography. Then they wonder why they can't cross 130 out of 200.
The guides and coaching material are summaries of Samacheer Kalvi. The original is always better than the summary.

Section 1: Tamil Nadu History — The Highest-Scoring Topic
Tamil Nadu History consistently gives 15–18 marks in Group 4 and 20–25 marks in Group 2. No other topic has this return on investment.
Primary Sources (Read these first)
Samacheer Kalvi Class 11 History — Tamil Nadu Chapters This is the most important single book for TNPSC TN History. The chapters covering Sangam Age, Pallava dynasty, Chola empire, Pandya kingdom, and Nayak period are exam gold. Read these chapters at least three times. Make your own notes with timelines.
Samacheer Kalvi Class 12 History — Nationalism and Independence Focus chapters: Indian National Movement, Tamil Nadu freedom fighters (Veerapandiya Kattabomman, Dheeran Chinnamalai, V.O. Chidambaram Pillai, Subramania Bharati, Marudhu Brothers), Partition, Republic formation.

Read these alongside Lakshmikanth.
Section 4: Geography — Tamil Nadu Focus First
Tamil Nadu Geography (Mandatory for All Groups)

Primary Source (Non-negotiable)
Samacheer Kalvi Science — Class 6, 7, 8, 9, 10 (all five books)
Read every chapter. Every chapter. The Class 6 chapter on "Food and Health" has appeared in TNPSC papers. The Class 10 chapter on "Heredity" has appeared. Nothing is too basic to skip.
Class 6–8 Science focus areas:
- Types of diseases (bacterial, viral, fungal, parasitic) — names and examples

- Human body organs: functions of liver, kidney, heart, lungs, pancreas
- Photosynthesis, respiration — basic equations
- States of matter, elements and compounds, physical vs chemical change

Section 7: Aptitude and Mathematics — Where Group 4 Is Won or Lost
Aptitude is 100 out of 200 marks in Group 4. It is also the most improvable section — unlike General Studies where you either know a historical fact or you don't, Aptitude rewards consistent practice.
R.S. Aggarwal — Quantitative Aptitude
Publisher: S. Chand Price: Rs. 450–550 Available: Amazon, Flipkart, any competitive exam bookshop
This is the standard Aptitude book for every competitive exam in India — TNPSC, SSC, Banking, Railways, all use this. Buy it once. It will serve you across multiple exam preparations.
How to use it:
- Work through 1 chapter per day — do not skip chapters.
- Read the worked examples in each chapter first. Understand the method.
- Then solve all the exercise questions (both A and B levels).
- Do not check the answer immediately — attempt the question fully first.
- After completing a chapter, revise it again after 3 days (spaced repetition).
Chapters for Group 4 (first 20 chapters sufficient): 1. Number System 2. HCF and LCM 3. Decimal Fractions 4. Simplification 5. Square Roots and Cube Roots 6. Average 7. Problems on Ages 8.

Section 8: Verbal and Non-Verbal Reasoning
R.S. Aggarwal — Verbal and Non-Verbal Reasoning
Publisher: S. Chand Price: Rs. 450 Available: Amazon, Flipkart, all bookshops
Buy this alongside the Quantitative Aptitude book. Both are by R.S. Aggarwal, both by S. Chand — together they cover the entire Aptitude paper.
Verbal Reasoning chapters (prioritise these for TNPSC):
- Number Series — fill the missing term; find the odd one out
- Alphabet and Letter Series — very common in TNPSC
- Analogy (Word analogy, Number analogy) — 5–8 questions per paper
- Blood Relations — draw a family tree for each question, do not solve mentally
- Direction and Distance — draw the path as you read; never visualise
- Coding-Decoding — look for the pattern in the code shift
- Seating Arrangement — use a table/circle diagram
Non-Verbal Reasoning: TNPSC uses less non-verbal (figure-based) reasoning than Banking exams. Practice the Mirror Images, Water Images, and Pattern Completion chapters — these occasionally appear.
Daily practice target: Once you start this book, solve 20–30 reasoning questions every single day. Reasoning speed improves only with daily practice — not with a single heavy session.
Section 9: Tamil Language
Sura's TNPSC Tamil (Tamil medium, Rs. 150–250)
Covers the Tamil portion of the exam: grammar (இலக்கணம்), Thirukkural, Tamil literature questions. This book is structured specifically for TNPSC and covers exactly what the exam tests.
Nila Publications TNPSC Tamil (Rs. 200–300) Popular among Tamil medium aspirants, especially in districts outside Chennai. Alternative to Sura's Tamil — both are good. Buy whichever is more easily available in your area.
What to focus on in Tamil:
Tamil Grammar (இலக்கணம்) — most marks come from here:
- வினை (Verb): வினைமுற்று, வினையெச்சம், வினையாலணையும் பெயர்
- பெயர் (Noun): திணை, பால், வேற்றுமை (8 case suffixes)
- சொல் (Word): இடைச்சொல், உரிச்சொல், வேர்ச்சொல்
- எழுத்து (Letter): உயிரெழுத்து, மெய்யெழுத்து, உயிர்மெய்
- புணர்ச்சி (Sandhi): விகாரப் புணர்ச்சி, இயல்பு புணர்ச்சி rules
Thirukkural:
- All 133 chapters (அதிகாரம்) and their names — memorise the chapter titles
- First couplet of each chapter is commonly tested
- Key kurals from: அறத்துப்பால் (Virtue), பொருட்பால் (Wealth), காமத்துப்பால் (Love)
Sangam Literature basics:
- Five Sangam periods and their Tamil names
- Major Sangam works: Purananuru, Akananuru, Kuruntokai, Silappatikaram, Manimekalai
- Tolkappiyam — first Tamil grammar book, by Tolkappiyar
Section 10: Current Affairs
Dinamalar or Dinamani — Daily Newspaper
Price: Rs. 5–7 per day / Rs. 150–200 per month subscription
Reading a Tamil newspaper daily is the only way to stay current with Tamil Nadu-specific news that TNPSC tests. International and national news matters too, but TNPSC Group 4 disproportionately tests Tamil Nadu state events.
What to read every day:
- Tamil Nadu government schemes: new housing schemes, welfare payments, farmer relief programmes
- Chief Minister and Governor: new appointments, inaugurations, key orders
- High Court and Supreme Court: significant judgments affecting TN
- Major sports: Tamil Nadu players in national/international events, sports awards
- Awards: Padma awards for TN people, national awards for TN organisations
How to use it: Keep a small notebook. Every day, write 5–8 items in this format:
| `[Date] | [Topic] | [Key fact]` |
|---|
| Example: `Jan 5, 2025 | TN Govt | Announced Kalaignar Magalir Urimai Thittam — Rs. 1,000/month to eligible women` |
|---|
Review this notebook weekly. It becomes your Current Affairs revision bank.
Sura's Monthly Current Affairs Magazine
Price: Rs. 50–60 per issue Available: TNPSC book stalls, Sura's website, Amazon subscription
Buy every month without fail. The Tamil Nadu section of this magazine is its most valuable part — it compiles all major TN state events in organised form. Read the TN section first, then national, then international.
Winmeen.com — Free Online Resource
The best free TNPSC resource available. Daily current affairs quizzes, TNPSC-focused mock tests, previous year papers with solutions, subject-wise practice tests.
Bookmark it. Use it daily for 20–30 minutes.
Section 11: All-in-One Combined Guides
These guides collect and summarise material from Samacheer Kalvi and other primary sources into a single book. They are useful for revision and for candidates who want a quick overview before going deeper into primary sources.
| Publisher | Guide | Price | Best For |
|---|---|---|---|
| Sura Books | TNPSC Group 4 Study Material | Rs. 400–550 | Group 4 and VAO beginners |
| Sura Books | TNPSC Group 2 Study Material | Rs. 550–700 | Group 2 and 2A aspirants |
| Vettri Publications | TNPSC Combined Guide | Rs. 350–500 | Alternative to Sura's |
| Nila Publications | TNPSC Tamil Guide | Rs. 200–350 | Tamil medium aspirants |
| Race Institute | TNPSC Study Material | Rs. 800–1,200 | Group 1 and Group 2 Main aspirants |
Honest assessment: Every one of these guides is a condensed version of Samacheer Kalvi books. Their practice questions and Q&A sections are genuinely useful. Their explanations are faster to read than Samacheer.
But if you rely only on these guides and skip Samacheer Kalvi — you will miss questions. TNPSC examiners write questions from the original textbooks. A guide that covers 5 points from a Samacheer chapter with 15 points will leave you unable to answer the other 10.
Correct way to use them: Read Samacheer first. Use the guide for revision after you have read the primary source. Use the practice questions section every week.
Section 12: Online Free Resources
All of these are free. Use them throughout your preparation, not just at the end.

Final Buying Guide — What to Spend at Each Level
Do not overspend. The most expensive preparation is not the most effective one. Samacheer Kalvi books are free.
| Level | Must Buy | Optional | Total Budget |
|---|---|---|---|
| Group 4 beginner | Samacheer books (free PDF) + Sura's Group 4 Guide (Rs. 500) + RS Aggarwal Aptitude (Rs. 500) | Lucent's Science (Rs. 250), Sura's Tamil (Rs. 200) | Rs. 1,000–1,500 |
| Group 2 aspirant | All above + M. Lakshmikanth (Rs. 650) + Ramesh Singh Economy (Rs. 750) + NCERT set (free) | Bipan Chandra Modern India (Rs. 300), GC Leong Geography (Rs. 450) | Rs. 2,500–3,500 |
| Group 1 aspirant | All the above + RS Aggarwal complete + GC Leong + Monthly Current Affairs (Rs. 720/year) | Coaching institute notes, test series (Rs. 2,000–5,000) | Rs. 4,000–6,000 |
What not to waste money on:
- Printed coaching materials before you have read Samacheer — they are summaries, not sources
- YouTube "shortcut tricks" channels — TNPSC does not reward shortcuts in General Studies
- Expensive test series without first completing the syllabus — mocks are for revision, not for learning
What is worth spending on:
- A good A4 notebook for each subject — writing your own notes doubles retention
- Monthly current affairs magazine (Rs. 50/month) — genuinely useful and non-replaceable
- R.S. Aggarwal books — used for multiple exams, worth every rupee
