BPSC TRE Exam Pattern 2026: Single Paper of 150 Marks
BPSC TRE Exam Pattern 2026: Single Paper of 150 Marks
TRE 4.0 is a single written paper. One sitting, 150 questions, 150 marks, 2 hours 30 minutes, OMR sheet, no interview. If you have been preparing for a two stage exam, stop and read this page, because the structure changed on 27 August 2026.
The part that decides your selection is smaller than the paper. Only 120 of those 150 marks enter the merit list. Understanding which 120 is the single most useful thing you can do this week.
What changed
Note the first row. Prelims was never a TRE feature. It appeared for the first time in Advertisement 14/2026 and was withdrawn nine days later. Anyone telling you that TRE 3.0 had a Prelims is wrong.
BPSC has not yet published the revised advertisement that records the single stage decision in an official document. Prepare on the single paper structure and watch bpsc.bihar.gov.in for the reissue.
The paper structure
This applies to Class 6-8, Class 9-10 and Class 11-12. Part III is the subject you applied in, so a PGT Chemistry candidate answers 80 marks of Chemistry while a TGT Sanskrit candidate answers 80 marks of Sanskrit.
Class 1-5 is built differently
There is no concerned subject paper at the primary level, and the reason is practical. A Class 1-5 teacher in Bihar teaches everything, from Hindi to environmental studies to arithmetic, so the paper tests broad general studies rather than one specialisation.
The merit total is still 120. What changes is where those 120 marks come from. A primary candidate carries the entire merit load in General Studies, which makes that section far heavier than it looks on the Class 6-12 table.
Marking scheme and the Option E trap
Each question has five options, A to E. Option E means not attempted. It carries zero marks and no penalty.
Here is the trap. Leaving a question completely blank is not free. It costs the same -1/3 as a wrong answer. If you want to skip a question, you must physically darken the E bubble. There is no passive way out of a question in this exam.
Work the arithmetic on a 20 question doubt list. Skip them by bubbling E and you lose nothing. Leave all twenty blank and you have handed back 6.67 marks before the evaluator has looked at a single answer. In a cycle where subject cut-offs in TRE 3.0 sat in the eighties and nineties, 6.67 marks is a rank band.
When guessing is worth it
With five options and a 1/3 penalty, a blind guess is close to break even over a long run. That is not the useful case. The useful case is elimination. Knock out two options and your odds go to one in three against a 1/3 cost, which turns clearly positive. Knock out three and you should always attempt.
The rule that works in the hall: if you can rule out two options, mark it. If you cannot rule out anything, mark E and move on. The preparation strategy page works this out in more detail with a time budget.
Language is a gate, not a scoring section
Part I carries 30 marks and none of them reach your merit score. You need 30% of 30, which is 9 marks, to stay in the race.
Nine marks out of thirty. That is the whole requirement. A candidate who scores 28 in language and one who scores 9 sit at exactly the same place in the merit list, assuming the rest matches.
This is where preparation time gets wasted every cycle. Aspirants polish grammar for weeks because language feels tractable, while the 80 mark subject paper waits. Clear the gate and leave.
Category-wise qualifying percentage
The 32% slab for women and Divyang candidates applies to Bihar domicile holders only.
Qualifying marks and cut-off are different things and the distinction matters. Qualifying marks decide whether you are counted at all. The cut-off, which moves by level, subject, district and category, decides whether you are selected. See cut off trends for how far apart those two lines sat in earlier cycles.
No interview at any stage
There is no interview, no personality test and no viva in TRE. Selection rests on the written paper, subject to document verification and the guest teacher weightage where applicable.
Guest teachers receive 5 marks per year of service up to a maximum of 25 marks, subject to Patna High Court LPA No. 593/2024.
How the 120 merit marks should shape your study
Two thirds of your selection comes from one section. Most candidates do not study in that ratio. They study general studies because current affairs material is abundant and free, and they study subject content last because it is harder and less social.
That is the inversion this exam punishes. For a Class 1-5 candidate the ratio flips completely, with all 120 merit marks in General Studies, so primary aspirants should read the detailed syllabus carefully before copying a Class 9-12 study plan.
ExamAtlas has free TRE General Studies mock tests with topic-wise accuracy analytics, which is the fastest way to find out whether your 40 marks are safe or just familiar.
A worked example of how the score is built
Take a Class 9-10 Mathematics candidate who attempts the paper like this.
Merit score here is 23.00 plus 48.67, which is 71.67 out of 120. The 12 language marks do nothing beyond clearing the 9 mark gate.
Now change one thing. Suppose this candidate had left those 25 uncertain questions blank instead of marking E. The penalty would apply to all of them, costing another 8.33 marks and dropping the merit score to roughly 63. Same knowledge, same paper, one bubbling habit, eight marks.
Exam day mechanics
- Mode is offline, answers marked on an OMR sheet with the prescribed pen.
- 150 questions in 150 minutes leaves exactly one minute per question, with no reading time bonus.
- Five bubbles per question means the OMR sheet is wider than the four option sheets you may have practised on. Practise on a five option sheet at least twice.
- Fill E deliberately, not in the last two minutes. Rushed E marking is how candidates end up with half filled bubbles that scan as blank.

Frequently asked questions
Is BPSC TRE 4.0 single stage or two stage?
Single stage. The Bihar CM announced on 27 August 2026 that TRE 4.0 will be held in one stage, withdrawing the Prelims plus Mains structure printed in Advertisement 14/2026. The revised advertisement confirming this is awaited.
How many marks count for merit in BPSC TRE 4.0?
120 marks. General Studies contributes 40 and the concerned subject 80. The 30 mark language section is qualifying only and does not enter merit. For Class 1-5, all 120 merit marks come from General Studies.
Is there negative marking in BPSC TRE?
Yes. A wrong answer costs 1/3 mark and a fully blank question also costs 1/3 mark. Only option E, meaning not attempted, carries no penalty.
What is option E in the BPSC TRE OMR sheet?
Option E stands for not attempted. Marking it gives you zero marks with no deduction. It is the only safe way to skip a question, since leaving the row blank is penalised.
How many marks do I need in the language section?
30% of 30 marks, which is 9 marks. Scoring above 9 gives you no merit benefit at all.
Does Class 1-5 have a subject paper?
No. The primary level paper has 30 marks of language, qualifying only, and 120 marks of General Studies which carries the full merit weight.
Is there an interview in BPSC TRE 4.0?
No. There is no interview at any stage of the selection process.
How long is the BPSC TRE 4.0 paper?
2 hours 30 minutes for 150 questions, offline on an OMR sheet.
Final word
The pattern is simpler than the news cycle around it suggests. One paper, 120 marks that matter, two thirds of them in your own subject, and one rule about blank answers that quietly costs candidates marks every year.
When the revised advertisement arrives, check one thing first. Not the structure, which the CM has already settled, but whether the subject-wise post count at your level has moved.
