After the TNPSC Group 1 Preliminary Examination of 27 September 2026 we read all 200 questions in booklet CCSEI-P26 and checked every one of them, by hand, against the three sets we actually teach from — past TNPSC papers, our own Home Test Batch, and our Maths Book.
2026 செப்டம்பர் 27ஆம் தேதி நடைபெற்ற குரூப் 1 முதல்நிலைத் தேர்வின் 200 வினாக்களையும், நாங்கள் பயிற்றுவிக்கும் மூன்று தொகுப்புகளுடன் — கடந்தகால வினாத்தாள்கள், எங்கள் வீட்டுத் தேர்வுத் தொகுதி, எங்கள் கணக்குப் புத்தகம் — ஒவ்வொன்றாக ஒப்பிட்டுப் பார்த்தோம்.
40 of 200
questions a student working through our material would already have met — 7 word for word and 33 as the same question re-worded, or the same sum with new numbers. That is 20% of the paper.
A further 96 questions sat on ground we had covered with a different fact tested, leaving 64 with nothing comparable in any of the three sets.

How the 200 questions graded
| Verdict | Questions | Meaning |
|---|---|---|
| Word for word | 7 | Same question, same data |
| Same question | 33 | Re-worded, or the same sum re-numbered |
| Same ground | 96 | Area we had covered, a different fact tested |
| Not seen | 64 | Nothing comparable in our material |
What we checked against
| Source set | Questions in it | Strong matches |
|---|---|---|
| 83 past TNPSC papers | 7,783 | 24 |
| 25 Home Test Batch papers | 2,536 | 20 |
| 37 Maths Book chapters | 2,909 | 11 |
These add up to more than 40 because several questions turned up in two of the sets, and one turned up in all three.
The seven that came back word for word
Same question, same data. A student who had worked these would have read the exam question and recognised it on sight.
QUESTION 45
Which one of the following is not a fiscal instrument?
(A) Taxation · (B) Bank Rate · (C) Public expenditure · (D) Public Debt
Identical question — which is not a fiscal policy instrument, with the same options: bank rate, taxation, public debt.
QUESTION 62
The Right of Children to Free and Compulsory Education Act ensures quality education to which age group?
(A) 0–5 years · (B) 5–10 years · (C) 1–5 years · (D) 6–14 years

QUESTION 66
In Tamil Nadu the Chief Minister’s Girl Child Protection Scheme was introduced in the year ________
(A) 1990 · (B) 1991 · (C) 1992 · (D) 1993
Identical — the year the scheme started, with 1992 among the options.
Our test states the scheme was introduced in 1992 — exactly the fact asked.
QUESTION 90
The dimensions of a brick are 24 cm × 12 cm × 8 cm. How many such bricks are required to build a wall 20 m long, 48 cm wide and 6 m high?
(A) 22000 · (B) 21000 · (C) 23000 · (D) 25000
Identical brick (24×12×8) and wall (20 m × 48 cm × 6 m) data.
Same bricks-per-wall volume-division mechanic, different dimensions.
QUESTION 91

(A) Rs. 12 · (B) Rs. 20 · (C) Rs. 61 · (D) Rs. 51
Identical — CI minus SI for P = 8000, r = 5%, n = 3 years.
The same CI−SI question with identical P = 8000, r = 5%, n = 3.
Same CI−SI difference, same three values.
QUESTION 173
The Military General who suppressed the Vellore Mutiny was ________
(A) George Carmichael Smyth · (B) Colonel Robert Rollo Gillespie · (C) John Nicholson · (D) William Hodson
Identical stem and identical four names.
QUESTION 188
10 persons begin a job together but after some days 4 leave. The job that could have been done in 40 days takes 50. How many days after the start did the 4 leave?
(A) 20 days · (B) 30 days · (C) 35 days · (D) 25 days
Verbatim the same problem — 10 persons, 4 leave, 40 days becomes 50.
Question 91 is the one to point at. The identical compound-interest-minus-simple-interest sum on ₹8,000 at 5% for 3 years appears in all three of our sets at once — a past paper, a Home Test Batch paper and the Maths Book. Three separate chances to have already solved it before walking into the hall.
The thirty-three asked again
Re-worded, or the same sum with the numbers changed. The fact being tested, or the method being used, is the one we had already drilled.
QUESTION 4

Same disease–pollutant matching: Minamata, Itai-Itai, blue baby, mercury, cadmium, nitrate.

What this says about how to prepare
The 96 “same ground” questions matter as much as the 40 repeats. They show TNPSC coming back to the same syllabus territory — Articles of the Constitution, Tamil Nadu welfare schemes, the freedom-struggle chronology, percentage and work-rate sums — while changing the specific fact asked.
Working past papers alone gets you the 24. Working past papers with a test batch and a worked maths book is what takes it to 40 — and the aptitude section is where our own material did the heavy lifting: of the questions from Q90 onwards that repeated, nearly all came from the Home Test Batch or the Maths Book rather than from an old paper.
கடந்தகால வினாத்தாள்களை மட்டும் பயின்றால் 24 வினாக்கள். வினாத்தாள்கள், தேர்வுத் தொகுதி, கணக்குப் புத்தகம் மூன்றையும் சேர்த்துப் பயின்றால் 40 வினாக்கள். குறிப்பாக திறனறித் தேர்வுப் பகுதியில் எங்களுடைய பயிற்சிப் பொருட்களே அதிகம் உதவின.
How we graded it
Every match above was read and judged by hand on the question stems and the options, with no answer key used on either side. Word for word means the same question with the same data. Same question means the wording changed but the fact or the method did not, or a sum kept its mechanic and changed its numbers. Same ground means the topic had been covered but the specific fact asked was different — those are counted separately and are not claimed as repeats.
