Alerts and Updates for BPSC TRE Higher Secondary Mathematics

Mathematics is the one subject at this level where a slice of Part II overlaps the subject itself: the reported general studies content includes elementary mathematics alongside general awareness, general science, the Indian national movement and geography. The reported Mathematics content for Part III spans number theory, algebra, trigonometry, coordinate geometry, calculus, statistics and probability. Sources disagree on negative marking, with most reporting a one-third deduction for a wrong answer and two reporting none. Reported minimum qualifying marks are 40 per cent for general candidates, 36.5 per cent for backward and extremely backward classes and 32 per cent for SC and ST, with one outlet giving 34 per cent for EBC. On a 150-mark paper the general floor of 60 marks is far below the 83 reported as the Mathematics unreserved cut-off last round, which confirms that in this subject the competition, not the threshold, sets the entry price. 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 and every level in TRE 4.0; there is no separate Mathematics notification, form or exam date. The exam window and the application closing date are the two items still unconfirmed, and both should be rechecked on the BPSC portal before being relied on.

Mathematics candidates most often misjudge this exam by assuming that a subject they know well will carry them. On the reported TRE 3.0 numbers it did not: the unreserved cut-off of 83 out of 150 was the highest in the class 11-12 table, more than twice the 40 reported for Physics in the same round. With only 657 posts against 1,758 for Physics and 3,695 for Chemistry, Mathematics is the scarce subject in the science group, and the cut-off reflects that scarcity rather than any special difficulty in the paper.

The PW subject-wise table gives Mathematics 657 posts out of 16,101 at higher secondary level, roughly four per cent of the class 11-12 pool and about a third of the Physics allocation. Two structural facts follow. First, the supply of applicants is large, because every science and commerce graduate route in Bihar produces mathematics post-graduates and the subject has no laboratory bottleneck. Second, the posts are then split by category and by the reported 35 per cent horizontal reservation for women domiciled in Bihar. An unreserved male candidate is realistically competing inside a few hundred seats across the entire state.

Adda247 reports TRE 3.0 Mathematics cut-offs of 83 for unreserved men, 66 for unreserved women, 63 EWS, 69 BC, 61 EBC and 39 SC, out of 150. Under the TRE 4.0 split, 83 is unreachable from the subject block alone, because Part III is only 80 marks and the reported qualifying language part contributes nothing. Even a perfect 80 in Mathematics would need three general studies marks on top. In practice an unreserved candidate is looking at something like 62 to 68 in the subject block plus 18 to 22 in general studies. That arithmetic makes general studies non-optional, not a supplement.

The reported Mathematics content is number theory, algebra, trigonometry, coordinate geometry, calculus, statistics and probability, and Careerpower places it at graduation to post-graduate standard rather than at plus two level. The eligible degree titles are reported as Mathematics or Applied Mathematics at post-graduate level. No unit-wise weighting has been published, so an even split across those seven heads is the defensible planning assumption. Candidates who trained on a pure mathematics syllabus should note that statistics and probability are named explicitly and are the areas most often left thin by algebra-and-analysis specialists.

One hundred and fifty questions in 150 minutes gives one minute per question across the whole paper, and Mathematics is the only subject at this level where a substantial share of questions demand working rather than recall. Since the 30 language and 40 general studies questions are largely recall and can be cleared quickly, the realistic budget is to finish Parts I and II in about 45 minutes and leave 105 minutes for the 80 subject questions. Candidates who solve in the order printed tend to lose the general studies marks they cannot afford to lose, given the cut-off arithmetic above.

Adda247, PW, Careerpower's notification page and Notifyhere report a deduction of one third of a mark for a wrong answer in TRE 4.0, with Notifyhere adding that unattempted questions are also penalised; Careerpower's syllabus page and Teaching Pariksha report no deduction. BPSC's own wording has not been read here. Mathematics candidates are relatively insulated either way, because a worked answer can usually be verified rather than guessed, but the asymmetry matters in general studies, where a one-in-four blind guess is break-even at best under a one-third penalty and clearly negative if the eliminated options are not genuinely eliminated.
