The TNPSC CTS 2026 (Combined Technical Services Examination) written exam is around the corner, and one of the most common questions candidates search for is “where do I get reliable TNPSC CTS study notes?” This blog gives you exam-ready, syllabus-based study notes for Paper I — the common paper for every CTS post (Degree and Diploma/ITI level alike) — covering Tamil Eligibility Test, General Studies, and Aptitude & Mental Ability. These notes have been prepared by Entri experts strictly as per the latest official TNPSC CTS syllabus, so you can start revising with confidence instead of hunting across multiple sources.
Why Paper I Notes Matter Most for Every TNSPC CTS Candidate
TNPSC CTS covers over 80 different posts across Interview and Non-Interview categories, and Paper II (the Subject Paper) differs post to post — Engineering, Accountancy, Law, Statistics, and more. But Paper I is identical for almost every candidate, regardless of which post or department you’re applying for. That makes it the single highest-leverage section to prepare well, since strong Paper I marks give every candidate — no matter their technical subject — a real shot at qualifying.
TNPSC CTS Paper I – Exam Pattern 2026
| Part | Subject | Standard | Questions | Marks | Nature |
|---|---|---|---|---|---|
| Part A | Tamil Eligibility Test | SSLC | 100 | 150 | Qualifying only (min. 40% / 60 marks required) |
| Part B | General Studies | Degree (AE posts) / Diploma or SSLC (Diploma-ITI posts) | 75 | 150 | Counted for ranking |
| Part C | Aptitude & Mental Ability | SSLC | 25 | 150* | Counted for ranking |
| Total | — | — | 200 | 300 (Parts A+B+C) | 3 Hours |
*Marks distribution for Part C varies slightly by notification year — always cross-check with the current official notification.
Only Part B + Part C marks (not Part A) are added to your Paper II score for the final merit list, so Tamil Eligibility Test is a qualifying hurdle, while General Studies and Aptitude directly decide your rank.

This is a qualifying paper, but a large number of candidates lose their entire attempt by underestimating it. Aim to comfortably clear the 40% (60/150) cutoff.
Core areas to revise:
- Basic Tamil Grammar (இலக்கணம்): எழுத்து, சொல், தொடர் இலக்கணம் அடிப்படைகள்; பிழையின்றி எழுதுதல்
- Vocabulary & Synonyms/Antonyms (இணைச்சொல் / எதிர்ச்சொல்)
- Comprehension passages (உரைநடைப் புரிதல்) — practice SSLC-level Tamil textbook passages
- Translation sense (English–Tamil basic equivalents) for common government/administrative terms
- Idioms and proverbs (மரபுத்தொடர்/பழமொழிகள்) commonly asked in TNPSC-level tests
Entri expert tip: Since this paper only needs a 40% qualifying score, don’t over-invest time here if your Tamil medium schooling is strong — spend saved hours on General Studies and Aptitude instead, where marks directly count.

TNPSC CTS 2026 General Studies — Study Notes (75 Questions, 150 Marks)
General Studies carries the highest weight among the ranking-counted sections, so this deserves the largest share of your Paper I study time. Based on the official syllabus, focus your notes around these five pillars:
a) History, Culture & Geography of India and Tamil Nadu
- Indian National Movement — key phases, leaders, and events
- Tamil Nadu history: Sangam age, Chola-Chera-Pandya administration, temple architecture
- Physical, economic, and social geography of India with special focus on Tamil Nadu’s rivers, soil types, and industries
b) Indian Polity and Constitution
- Fundamental Rights, Directive Principles, and Fundamental Duties
- Union and State government structure, Panchayati Raj system
- Recent constitutional amendments and current governance topics
c) Indian Economy
- Five-Year Plans and NITI Aayog, basic economic indicators (GDP, inflation, fiscal deficit)
- Tamil Nadu-specific economic schemes and budget highlights
- Banking, taxation basics (GST), and financial inclusion programs
d) General Science
- Physics, Chemistry, and Biology at a general-awareness (SSLC-Degree) level
- Recent science and technology developments relevant to competitive exams
- Environmental science: pollution, biodiversity, climate change basics
e) Current Affairs (National, International & Tamil Nadu-specific)
- Government schemes launched in the last 12 months
- Appointments, awards, and honours
- Sports, defence, and international relations highlights
- Tamil Nadu government policies, budget announcements, and welfare schemes
Build a rolling one-page current affairs summary every week rather than trying to memorise a year’s worth of news right before the exam — TNPSC tends to test recent and Tamil Nadu-specific events more than generic national news.

Aptitude & Mental Ability — TNPSC CTS Study Notes 2026 (25 Questions, SSLC Standard)
This is the most scoring section per question if you practice regularly, since it tests skill rather than memory.
Quantitative Aptitude
- Simplification, Percentage, HCF & LCM
- Ratio & Proportion, Simple Interest, Compound Interest
- Area, Volume, Time & Work, Time-Speed-Distance
- Profit & Loss
Reasoning & Mental Ability
- Analogies, Series Completion, Coding-Decoding
- Blood Relations, Seating Arrangement, Syllogism
- Mirror Images, Embedded Figures, Paper Folding & Cutting
- Data Interpretation, Data Sufficiency, Venn Diagrams
- Logical Deduction and Logical Sequences
Since only 25 questions are asked from this section, don’t chase every topic equally — prioritise Simplification, Percentage, Time & Work, and Blood Relations/Coding-Decoding first, since these appear most consistently across past TNPSC-pattern papers.

What About Paper II (Subject Paper) Notes?
Paper II is the post-specific Subject Paper (Engineering, Accountancy, Law, Statistics, Agriculture, and 15+ other technical/professional subjects depending on the post you choose), carrying 300 of the total 450 ranking marks. Because this differs by post and qualification, it needs a separate, subject-specific notes set rather than one common file. Check the full TNPSC CTS syllabus and post list to identify your exact Subject Paper, and refer to your qualification-specific standard textbooks for that portion.
