Checked 22 September 2026. The phase count is actively disputed and could change with a single BPSC notice. The paper structure below is stable across both outcomes. Re-check the exam calendar before relying on the phase count.
Where other pages get this wrong
Nobody has overruled anybody. BPSC and the state government are both on record, saying different things.
Commonly published instead: Most pages state flatly that TRE 4.0 is a single-phase exam, citing the 27 August announcement, and quietly drop the fact that BPSC’s own exam calendar still lists it under two phases.
BPSC’s annual exam calendar of 14 August 2026 places TRE 4.0 at serial 30 under the heading "2 PHASE EXAMS (PT + MAINS)". On 27 August the Chief Minister announced a single stage. A Chief Minister’s announcement is a political commitment; the pattern changes when the Commission issues a corrigendum. As of the date on this page, it has not.
If you are preparing for BPSC TRE 4.0 right now, you have probably read one page telling you there is a preliminary test and another telling you there is not. Both pages are quoting something real. Neither is quoting the thing that would settle it, because that thing does not exist yet.
This page does three things. It lays out exactly who said what and when, so you can judge the dispute yourself. It gives you the question paper structure, which is confirmed and — this is the useful part — identical under both scenarios. And it is honest about the several things that are still genuinely unknown, including negative marking, where four reputable sources give four incompatible answers.
The timeline, dated
| Date | What | Meaning |
|---|---|---|
| 18 Aug 2026 | BPSC issues Advertisement 14/2026 for 32,388 posts | The recruitment formally exists |
| 14 Aug 2026 | BPSC exam calendar lists TRE 4.0 at serial 30 under "2 PHASE EXAMS (PT + MAINS)" | The Commission’s own published position: two phases |
| Aug 2026 | "One Exam, One Result" (एक परीक्षा, एक परिणाम) campaign; a ten-day hunger strike by aspirants | Organised pressure against a two-phase format |
| 27 Aug 2026 | CM Samrat Choudhary announces TRE 4.0 will be single-stage, as part of a package of ten decisions; a Patna High Court judge-led panel is set up on exam reform | A state government commitment — not a Commission order |
| 1-30 Sep 2026 | The original application window, postponed "for procedural changes" | Applications cannot open while the phase count is contested |
| 22 Sep 2026 | No BPSC corrigendum on the pattern has been published | The conflict is live |
The sequence matters. The calendar predates the announcement by thirteen days, so "the calendar is simply out of date" is a reasonable reading — but it is a reading, not a fact, and BPSC has had close to a month to publish a correction and has not. The application window slipping is the strongest circumstantial evidence that something structural is being rewritten behind the scenes, because the Commission cannot sensibly invite applications while the number of phases is unsettled.
What "One Exam, One Result" actually won
- The demand was एक परीक्षा, एक परिणाम — one exam, one result — against a format where candidates sit a screening test and then a second, separate examination.
- It was settled on 27 August as a package of ten decisions, not a single concession.
- Single-phase TRE 4.0 was conceded outright.
- The broader principle of "one candidate, one result" was accepted only "as per existing rules" — which is to say, deferred.
- A reform panel headed by a Patna High Court judge was constituted, and it could move the pattern again.
Reported consistently across five outlets. None of them names an individual campaign leader — every account says "student representatives" or "aspirants". If you see a page crediting a particular coaching figure, it is not drawing on these reports.
The question paper — confirmed, and the same under both scenarios
This is the part you can act on today. Every source that describes the TRE 4.0 paper describes the same one: 150 questions, 150 marks, two hours thirty minutes, offline on an OMR sheet.
| Level | Part I (qualifying) | Part II | Part III | Counted for merit |
|---|---|---|---|---|
| Classes 1-5 | Language — 30 Q | General Studies — 120 Q | none | 120 marks |
| Classes 6-8 | Language — 30 Q | General Studies — 40 Q | Subject — 80 Q | 120 marks |
| Classes 9-10 | Language — 30 Q | General Studies — 40 Q | Subject — 80 Q | 120 marks |
| Classes 11-12 | Language — 30 Q | General Studies — 40 Q | Subject — 80 Q | 120 marks |
Where other pages get this wrong
Classes 1-5 has TWO parts, not three. General Studies is 120 of the 150 questions.
Commonly published instead: At least one widely-syndicated page prints an identical three-part structure — Language 30, General Studies 40, Subject 80 — across all four levels.
At primary level there is no subject paper. Language is 30 questions and qualifying; General Studies is the remaining 120 and carries 100% of your merit score. A Class 1-5 candidate who splits revision time as though General Studies were worth 40 marks is preparing for the wrong exam.
The consequence almost nobody states
- Part I (Language, 30 questions) is qualifying only. You must clear it at 30%, and then it is discarded.
- Your merit score is computed on the remaining 120 marks, not on 150.
- This is why published cut-offs look low. A cut-off of 75 is 75 out of 120 — that is 62.5%, not 50%.
- It also means Part I is a threshold to clear, not a place to win marks. Time spent pushing Language from 60% to 90% buys you nothing in the merit list.
We set out the arithmetic that proves the 120 base — including why a published cut-off of 39 is impossible on a 150 base — on the cut-off page linked at the foot of this article.
How this compares with TRE 3.0
TRE 3.0 was a single-stage examination. That is the fact that gives the protest its force: a preliminary test would not have been a continuation of the existing format but a new hurdle added to it. Read that way, the 27 August concession is less a reform than a reversion.
We are deliberately not publishing a TRE 1.0 and TRE 2.0 pattern comparison. We could not verify those two formats to the standard the rest of this page is held to, and a plausible-looking table of unverified structures would undermine the parts we can stand behind.
The fifth option, and why blind guessing is now pointless
BPSC is introducing a fifth answer option, E, meaning "Not Attempted". It has to be actively filled in. The reported marking scheme is the interesting part: a wrong answer costs one-third of a mark, choosing E costs nothing — and leaving the row completely blank also costs one-third of a mark. The penalty is for not engaging with the question, not for getting it wrong.
| What you do | Marks | When it is worth it |
|---|---|---|
| Correct answer | +1 | Always |
| Wrong answer | − 1/3 | Only as the result of a genuine attempt |
| Option E (Not Attempted) | 0 | When you have no basis to narrow the options |
| Row left completely blank | − 1/3 | Never — this is the new trap |
The guessing arithmetic, if the reported scheme holds
- Blind guess between five options with one-third negative: your expected return is exactly zero — identical to marking E, with added variance.
- Eliminate one option (1 in 4): expected +1/12 per question. Marginally worth it.
- Eliminate two (1 in 3): expected +1/9. Worth it.
- Eliminate three (1 in 2): expected +1/3. Clearly worth it.
- The rule that follows: never leave a row blank, and only guess once you have eliminated something.
This arithmetic is ours; the marking scheme it rests on is reported by a single publisher that does not cite a notification number. Treat the conclusion as sound only if the scheme is confirmed — which is exactly the sort of thing to check on the official notice before the exam.
Unresolved: Is there negative marking, and how much?
- One-third of a mark per wrong answer — Physics Wallah; Adda247 (which applies it to both stages).
- No negative marking at all — Career Power.
- No negative marking in the language sections only — Teaching Pariksha.
- One-third, with a blank row also penalised — Drishti IAS, in the context of the new option E.
Our position: We are not picking one. There is a likely explanation for the disagreement — TRE 3.0 genuinely had no negative marking, so pages saying "none" may simply be recycled TRE 3.0 copy that was never updated — but that is our reasoning, not a sourced fact. Prepare as though one-third negative marking applies, since that is the assumption that costs you nothing if you are wrong.
What to actually do while this is unresolved
The preparation is the same either way — here is why
- If TRE 4.0 is single-phase, the 150-question paper above is the exam.
- If a preliminary test returns, that same paper becomes the Mains, and a PT would be General Studies-based — which Part II preparation already covers.
- No scenario wastes the work. There is no branch of this where subject preparation for your level turns out to have been the wrong thing to do.
- Clear Part I (Language) at 30% and stop. It is a gate, not a scoring opportunity.
- Weight your revision by the merit base: at Classes 6-12 the subject paper is 80 of your 120 merit marks — two-thirds. At Classes 1-5, General Studies is all 120.
The one thing genuinely worth watching is the reform panel. A concession extracted by protest and delivered by announcement, with a judge-led committee still sitting, is not the same as a settled rule. Check the exam calendar and the notices page before the application window opens; that is where a change will appear first, and it will appear there before it appears on any coaching site.
Is BPSC TRE 4.0 one exam or two?
It is genuinely unsettled. BPSC’s exam calendar of 14 August 2026 lists TRE 4.0 under "2 PHASE EXAMS (PT + MAINS)". On 27 August 2026 the Chief Minister announced it would be single-stage. BPSC has published no corrigendum, so its own official document still says two phases. The practical answer is that the 150-question paper is what you prepare for under either outcome.
How many questions are in the BPSC TRE 4.0 paper?
150 questions for 150 marks in 2 hours 30 minutes, offline on an OMR sheet. Part I is Language (30 questions, qualifying at 30%, not counted in merit). At Classes 6-8, 9-10 and 11-12 the rest is General Studies (40) plus your subject (80). At Classes 1-5 there is no subject paper — General Studies is the full remaining 120 questions.
Is the BPSC TRE 4.0 exam out of 150 or 120 marks?
The paper is 150 marks, but merit is computed on 120. Part I Language is qualifying only: you must clear it at 30%, after which it is excluded from your score. This is why published cut-offs look lower than candidates expect — a cut-off of 75 means 75 out of 120, which is 62.5%.
Is there negative marking in BPSC TRE 4.0?
Sources disagree and we will not pick one. Physics Wallah and Adda247 report one-third of a mark deducted per wrong answer; Career Power reports none; Drishti IAS reports one-third alongside the new option E. TRE 3.0 had no negative marking, which may explain why some pages still say there is none. Prepare on the assumption that one-third negative marking applies.
What is option E in the BPSC exam?
A fifth answer option meaning "Not Attempted", which must be actively marked. As reported, choosing E scores zero with no penalty, a wrong answer costs one-third of a mark, and — the part to note — leaving the row entirely blank also costs one-third. If that scheme holds, you should never leave a row blank.
Does the Class 1-5 paper have a subject section?
No. Classes 1-5 has two parts only: Language (30 questions, qualifying) and General Studies (120 questions). General Studies carries your entire merit score at that level. Pages showing a uniform three-part structure across all four levels are wrong about primary.
Will the exam pattern change again before the exam?
It could. The single-phase decision came from a political announcement rather than a Commission order, and a Patna High Court judge-led panel on exam reform is still sitting. The authoritative place to check is BPSC’s exam calendar and notices page — a change appears there before it appears anywhere else.
When will BPSC TRE 4.0 applications open?
Not confirmed. The window was originally 1-30 September 2026 and was postponed for what BPSC described as procedural changes. A revised opening was reported for 21 September but did not hold. Given that the phase count is unresolved, a pattern corrigendum is a plausible reason for the delay — though BPSC has not said so.
