10 common TNPSC Group 4 mistakes, from the application to the exam hall

TNPSC Guide is not the official TNPSC website. Apply only on the official portal.

Checked on: 28.10.2026. On that day tnpsc.gov.in listed no addendum or corrigendum to this notification.

In Group 4, small mistakes can cost you your application or your marks, and all are avoidable. Here are ten, each with the reason it hurts, the fix and the page.

Page numbers are from the English PDF of Notification 11/2026, which is final in case of doubt (para 6.5, page 21). For the key dates in one place, see the Group 4 exam page.

What are the ten mistakes? At a glance

Which mistakes should I avoid when applying?

Mistakes 1 to 8 happen in the application; for the full walk-through, see how to apply, step by step.

1. Entering your details on an unofficial site

Applications are accepted online only, on the Commission's website only (para 1.3.1, page 1). The notification prints the address as www.tnpscexams.in. On 19.10.2026 and 21.10.2026 the application pages opened at apply.tnpscexams.in.

A form filled in anywhere else is not an application to the Commission, and your Aadhaar and mobile details may reach strangers. TNPSC Guide will never apply on your behalf, and we will never ask for your password or Aadhaar number.

2. Waiting until the last day

The last date is 05.11.2026, 11.59 PM (para 1.2, page 1). You have applied only when you press SUBMIT for the final submission (para 3.8.4, page 28).

In the last days the portal and the payment page may be slow. That is our advice, not a rule in the notification. Get your certificates ready and submit a few days ahead.

3. Registering on One Time Registration (OTR) a second time

Register on One Time Registration only once; it is valid for five years from the date of registration (Annexure I, para 2.1, page 23). Linking Aadhaar is mandatory to access or renew an existing OTR (para 2.5, page 23).

If you cannot log in to your old OTR, do not create a new one; ask the Commission. Toll-free: 1800 419 0958, on working days from 10.00 AM to 5.45 PM (para 9.1, page 21). E-mail: helpdesk@tnpscexams.in (para 9.2, page 21).

4. Not checking the SSLC details in your OTR

Your OTR details are the basis of every later application (para 2.6.3, page 23). If any SSLC detail is wrong, the application will be rejected after due process (para 2.6.1, page 23).

Check your name, date of birth and every number against your SSLC certificate, one by one.

5. Leaving out date-of-birth or age-concession documents

Your date of birth is checked against your SSLC or HSC mark sheet (para 4.1.6.1, page 8). If you claim an age concession and its document is missing, the candidature is rejected after due process (para 4.1.6.2, page 8).

For the certificates that are accepted, see Group 4 eligibility: age and proof of Tamil.

6. Choosing the fee concession Yes/No without thinking

In the application you choose "Yes" or "No" for the fee concession. That choice cannot be modified or edited after you submit (para 3.9.4, page 28).

Who is eligible for a fee exemption is set out in para 3.9.2 and Annexure II. Lists online do not agree with each other, so do not rely on them; read those two places yourself. Keep your own count of how often you have used the concession (para 3.9.4).

7. Not knowing about the proof of Tamil knowledge

This rule is separate from Part A of the paper. Upload the mark sheets or the test certificate when the Commission asks (para 4.4.2, page 16).

Without that proof, you must pass the Second Class Language Test (Full Test) in Tamil, conducted by TNPSC, within two years of appointment, or be discharged from service (para 4.4.3, page 16).

8. Missing the correction window

You can edit all the details of a submitted application until the last date, 05.11.2026 (Annexure I, para 3.11.1, page 29). After that, the Application Correction Window is open from 09.11.2026, 12.01 AM to 11.11.2026, 11.59 PM. After that, no change is allowed (paras 1.2 and 1.3.2, page 1). A claim added after you submit is not entertained (para 1.3.5, page 2).

Read your submitted copy again, note any mistake and fix it in the window. We cannot promise that any correction will be accepted. Filling the form correctly the first time is safest.

9. Underrating Part A Tamil

The paper has 200 questions for 300 marks (para 6, page 20). Part A, the Tamil Eligibility-cum-Scoring Test, has 100 questions for 150 marks. Part B General Studies (75 questions) and Part C Aptitude and Mental Ability (25 questions) are evaluated only if you score at least 60 in Part A (para 6.1, page 20).

Below 60 in Part A, even good General Studies marks are never counted. So do not leave Tamil for the end; give it time every day. We explain the seven units in how to study Part A Tamil.

A note on what you read online. Websites disagree about the age limit, the fee and the marking, and some PDF files spread wrong figures. Only Notification 11/2026 is final, so check every figure on its page there, in English or Tamil.

10. Leaving an OMR answer blank

The OMR answer sheet rules are in Annexure IV of the notification. Do not leave any question blank. If you do not know the answer, darken option E (para 1.6.2.5, page 68). For each question left blank, 0.5 mark is deducted from your total (para 1.10.2.2, page 72).

Simple arithmetic: leave 6 questions blank and you lose 3 marks. That sum is ours.

In mock tests, practise shading an OMR sheet, and check for blanks before you hand it in. On whether a wrong answer costs marks, see the FAQ below.

For the other rules, read exam pattern and OMR rules and the TNPSC OMR guidelines page.

Practical steps

1. Today, log in to your OTR and check your SSLC details and your Aadhaar link.
2. Put your date-of-birth, age-concession and Tamil-knowledge certificates in one folder.
3. Before you choose Yes or No for the fee concession, read para 3.9.2 and Annexure II.
4. Submit before 05.11.2026, 11.59 PM, not on the last day, and save a copy.
5. If you find a mistake, fix it in the correction window, 09.11.2026 to 11.11.2026.
6. Give Part A Tamil time every day, and note your Part A score on its own in every practice test.
