TNPSC negative marking: wrong answers are free, blanks are not

By the PrepMatic team · Updated 8 Oct 2026 · 6 min read

TNPSC does not deduct marks for wrong answers, but it does penalise blanks. In the Group 4 notification of 6 October 2026, every OMR question has five bubbles: options A to D and [E] "answer not known". Each question left completely blank costs 0.5 mark, deducted from your total. A wrong answer costs nothing. So in the objective papers where this rule applies, never leave a question empty: shade your best guess, or E.

Articles that say "TNPSC has no negative marking at all" leave out the blank-answer rule, and that omission can cost you marks. This page is part of the TNPSC exam guide.

The rule, line by line

All of this comes from Annexure IV (the OMR instructions) of the Group 4 2026 notification.

You must also record the number of questions you left unshaded, as the OMR instructions direct. Read Annexure IV of the current notification fully before exam day.

Why this changes how you attempt

Take a Group 4 paper in which there are 20 questions you cannot answer (the Group 4 study plan shows how to cut that number). This table shows the marks on those 20 questions, using expected values for the guesses.

The gap between blank and an informed guess is a 25-mark swing in this example, from nothing but how you fill the OMR. Because a wrong answer is free, a guess is never worse than [E] on marks alone. Option E exists so that a deliberate "don't know" isn't counted as a blank, not because it scores better.

Which papers does this apply to?

We verified the blank-answer rule in the Group 4 2026 notification. The OMR rules of other objective papers are printed in each notification's own annexure, so read the one for the exam you are sitting:

• Group 4: one OMR paper, 200 questions in 3 hours. Covered in the Group 4 exam pattern.
• Group 2 and Group 1 preliminary papers: also OMR-based objective papers of 200 questions and 300 marks. Check the notification for the OMR instructions of that cycle.
• Group 2A Main Paper II: computer-based, so there is no OMR sheet. Follow the on-screen instructions in the notification.
• Group 2 and Group 1 mains: descriptive papers with their own marking, covered on the Group 2 exam pattern and Group 1 exam pattern pages.

Qualifying marks and ranking marks are different things

TNPSC papers do two different jobs: some marks decide your rank, and some only decide whether you move on.

The Group 4 case is the odd one. Part A is both a gate and a scoring section: if you score below 40% (60 of 150) the Commission does not even evaluate Parts B and C, and Part A marks still count towards your rank. The Tamil eligibility test guide goes through it.

An attempt strategy for the OMR paper

Group 4 gives you 3 hours for 200 questions, an average of 54 seconds each. A plan you can rehearse:

1. Attempt all 200. Blank is the only choice with a guaranteed cost.
2. Two passes. On pass one, answer what you know and skip what needs thought, keeping track of the question numbers you skipped. On pass two, return to those with elimination.
3. Shade as you go. Don't leave 100 questions to copy at the end. Check the question number against the OMR row every 20 to 25 questions, because one skipped row shifts every later answer.
4. Fill the leftovers before time ends. In the last 10 to 15 minutes, shade something on every remaining question, a guess or E.
5. Budget the parts. One split to rehearse: about 65 minutes for Part A (Tamil), 60 for Part B (General Studies), 35 for Part C (Aptitude), and 20 for the final OMR check. Adjust after your first mocks.
6. Don't forget the admin marks. Thumb impression and register number carry penalties as shown above.

Practising it

When you take a full-length mock, re-score it yourself afterwards, using the 0.5 deduction for each question you left blank. Do it for three or four mocks and the habit of filling every row sticks. The TNPSC mock test guide covers how often to sit full papers and how to analyse them.

PrepMatic's full-length Group 4 mocks match the real paper's 200 questions in 180 minutes, so you can rehearse the pacing and the guess-or-E decision under the same clock. The result shows your subject-wise breakdown and the subject that cost you the most marks. You can choose Tamil as your exam language, so Part A questions appear in Tamil.

Frequently asked questions

Is there negative marking in TNPSC Group 4?

Not for wrong answers. The notification does not deduct marks for an incorrect option. It does deduct 0.5 mark for every question left completely blank, which is why the OMR sheet has an [E] "answer not known" bubble.

What is option E in the TNPSC OMR sheet?

Option [E] means "answer not known". Shading it counts as an attempt, so the blank penalty does not apply, but it earns no marks either. A guess among A to D carries the same zero penalty with a chance of scoring.

How many marks are deducted for a blank answer in TNPSC?

0.5 mark per question that is completely unshaded, deducted from the total. In Group 4 each question is worth 1.5 marks, so the penalty is one third of a question's value.

What is the minimum qualifying mark in TNPSC Group 4?

The 2026 notification sets 90 out of 300 for all communities, plus a minimum of 60 out of 150 in Part A (Tamil). Without the 60 in Part A, Parts B and C are not evaluated.

Do the Group 2 and Group 1 papers have the same blank-answer penalty?

We verified the rule in the Group 4 2026 notification. Read the OMR annexure of the Group 2 or Group 1 notification for your cycle, and for Group 2A Main Paper II note that the paper is computer-based.
