        <p>Chemistry is the largest single subject in the class 11-12 bracket of BPSC TRE 4. Physics Wallah, Testbook and Notifyhere all put the Chemistry higher secondary figure at 3,695 posts out of 16,101 at that level, roughly one post in four. Career Power's write-up of the same advertisement gives 3,811 instead, so the exact count should be read off BPSC's own vacancy annexure before anyone relies on it.</p>

        <p>The number of stages in TRE 4.0 is unresolved, and it is the single biggest open question in this cycle. BPSC's own exam calendar, dated 14 August 2026, lists TRE 4.0 at serial 30 with 32,388 vacancies under the heading 2 PHASE EXAMS (PT + MAINS), and records the exam date as TBD with the remark that the date of the PT shall be published after the completion of the advertisement period. On that document, TRE 4.0 is a two-stage recruitment with a screening preliminary test.</p>

        <p>On 27 August 2026, nine days after Advertisement 14/2026 was issued, Bihar Chief Minister Samrat Choudhary announced that TRE 4.0 would be held in a single phase, scrapping the PT and Mains structure. The announcement followed a campaign by candidate representatives under the slogan One Exam, One Result. This is a state government statement rather than a BPSC order, and it directly contradicts the Commission's own calendar.</p>

The Commission's notices page carries corrigenda for the 72nd CCE and notices on the Stenographer examination and the new fifth answer option, but nothing on TRE. The 14 August calendar still shows PT plus Mains and has not been revised. The unresolved pattern is the most plausible reason the application window was postponed for procedural changes, and candidates should expect the revised pattern and the reopened window to be announced together.</p>

The Chemistry paper for classes 11-12 at a glance

Chemistry itself is only 80 of the 150 questions in the main paper. Part I, the language section, carries 30 questions that do not add to merit but must clear 30 per cent, and the 40-question General Studies block does count. So a Chemistry specialist who scores heavily in Part III can still be overtaken by someone weaker in Chemistry but competent in Bihar-flavoured general awareness. Career Power, Adda247 and BiharHelp all report the same 30-40-80 split and the 2 hour 30 minute duration. Read the structure below as the pattern for the written examination, not as a settled number of stages. BPSC's calendar of 14 August 2026 places TRE 4.0 under two-phase PT plus Mains exams; the Chief Minister announced a single-phase exam on 27 August 2026; and BPSC has published no corrigendum resolving the two as of 22 September 2026. The question paper described here is the one candidates must prepare for either way, because a single-phase exam would use it and a two-phase exam would use it as the main paper.

This calendar is common to every subject in BPSC TRE 4 — Chemistry has no separate notification, no separate application window and no separate examination date. The December-January window and the mid-October confirmation are Adda247's expectation, not a BPSC announcement; Physics Wallah still carries the superseded 1 to 30 September window, which is one reason to check the commission's site rather than any aggregator.

The commonest mistake among Chemistry candidates is reading 3,695 posts as an easy field. It is the largest higher secondary subject in the advertisement, which means it also draws by far the largest applicant pool from Bihar's very deep M.Sc. Chemistry base. The second mistake is treating the 80-question Chemistry block as the whole paper when 40 General Studies questions carry merit weight and the language section can disqualify outright.

Chemistry at 3,695 posts is the single biggest higher secondary subject in TRE 4, ahead of Physics at 1,758 and English at about 1,321, as Physics Wallah's breakdown shows. Career Power's page reports 3,811 for the same advertisement, so the two published figures differ by over a hundred posts; the annexure to Advertisement No. 14/2026 is the only thing that settles it. Either way Chemistry is about a quarter of the 16,101 higher secondary posts. Large subject means large intake but also the largest competing cohort, and the district-wise split matters more than the state total, because allocation in earlier TRE rounds ran district by district and a popular district can close well above the subject cut-off.

Career Power's compilation of previous-round cut-offs puts the class 11-12 Chemistry unreserved mark at 41, with 39 for unreserved women, and leaves most reserved categories blank. Against the same compilation, Economics at that level closed near 73 and Computer Science near 63. A Chemistry mark in the low forties out of 150 is strikingly low next to those, which is consistent with a very large intake absorbing most of the qualified field rather than with an easy paper. These are aggregator-compiled numbers from an earlier TRE round, not BPSC's own subject-wise cut-off PDF, and a subject whose vacancy count changes between rounds will not repeat its cut-off.

Prepare the +2 syllabus, answer at PG depth

BPSC has not published a topic-wise Chemistry syllabus for TRE 4. BiharHelp reports the notification as saying subject papers draw on SCERT and NCERT content, while eligibility requires a master's degree in Chemistry or Biochemistry with B.Ed and Bihar STET Paper-II. The practical reading is that the class 11 and 12 NCERT Chemistry books define the topic list — physical, inorganic and organic in roughly equal measure, with coordination compounds, chemical kinetics, electrochemistry, thermodynamics, the p-block and named organic mechanisms recurring heavily — but that questions are set to separate postgraduates, so a candidate who can only recall the textbook statement without the underlying reasoning will lose the discriminating third of the paper.

Negative marking and Chemistry numericals

Both stages deduct 0.33 marks for a wrong answer, per Adda247's account of the selection process; Physics Wallah's page says 0.25, which is the one substantive disagreement among the sources on pattern. At either rate, Chemistry is the subject where the penalty bites hardest, because mole-concept, equilibrium, kinetics and electrochemistry items look solvable and consume three or four minutes each before yielding a wrong sign or a misread unit. With 150 questions in 150 minutes in the main paper the average is one minute per question, so a disciplined rule — attempt a numerical only if the route is visible within about twenty seconds — protects both the clock and the score.

Clear the gate before optimising the subject

BiharHelp reports minimum qualifying marks of 40 per cent for general candidates, 36.5 for BC, 34 for EBC and 32 for SC, ST, women and persons with benchmark disabilities, alongside a separate 30 per cent floor in the qualifying language section. Those are gates, not the merit line. A Chemistry candidate who spends every week on the subject and none on Part I is risking elimination on a paper that contributes nothing to rank. The same logic applies to the 40 General Studies questions, which at 40 of the 110 merit-bearing marks are more than a third of what decides the order, and which are cheaper to raise than the last few Chemistry marks.
