22 chapter playbooks behind 47.3 of the 50 questions

205 q - 4.96/paper - 42% HARD. The single heaviest chapter on recent papers. Seven subtopics, and the HARD is spread rather than concentrated (top two carry only 47%), so there is no cherry-pick here: you own the whole chapter or you lose ten marks.

228 q - 4.81/paper - 55% HARD. The largest chapter in the bank and the hardest of the cornerstones. Scalar Triple Product (71 q, 72% HARD) and Cross Product (66 q, 64%) carry 74% of its HARD between them, so this chapter DOES cherry-pick: secure Dot Product (50 q, 28% HARD) first.

183 q - 3.81/paper - 23% HARD. The cheapest cornerstone by some distance, and the best marks-per-hour chapter on the paper. Seven subtopics, none above 31% HARD; Approximations using Differentials is 11 q at 0% HARD.

144 q - 3.35/paper - 38% HARD. Six subtopics that split cleanly by SOLUTION METHOD, which is exactly how the questions are set. Order/Degree/Formation (33 q, 24% HARD) is recognition work and near-free; Linear (Integrating Factor) at 63% HARD is where the chapter gets expensive.

159 q - 3.35/paper - 51% HARD. A cornerstone you cannot skip and cannot rush. Substitution alone is 51 q; Trigonometric Integrals (Rational forms) runs 74% HARD, the highest of any subtopic in the subject. Foundations plus Trig Powers are 20 q at ~10% HARD - take those first.

141 q - 3.15/paper - 47% HARD. Method-pure subtopics, each drilling one technique. Inverse-trig differentiation (39 q) is the biggest single block. Derivative of One Function with respect to Another is only 7 q but 71% HARD - the worst marks-per-minute cell in the chapter.

46 q - 1.00/paper - 4% HARD. The lowest-HARD chapter in the subject, and one of its two subtopics (Objective Function, 23 q) has NEVER produced a HARD question. Two marks that should take under a minute. Do this first, every time.

115 q - 2.65/paper - 20% HARD. The highest-weight Quick-Win, worth over five marks a paper at a fifth the HARD rate of the calculus chapters. Classical Probability (21 q) runs 10% HARD; only Bayes and Conditional (26 q, 31%) has any real teeth.

88 q - 1.92/paper - 31% HARD. The one chapter in MHT-CET Maths with its own execution mode: 70% of its stems ask which statement is true, against roughly 0% everywhere else. Its 31% HARD overstates the cost, because the difficulty is front-loaded into learning ONE technique (build the truth table) that then applies to every question.

60 q - 1.27/paper - 22% HARD. A small, closed chapter with four subtopics and no surprises. Mean, Variance and Standard Deviation of a binomial variable (15 q) runs 13% HARD and is pure formula recall.

46 q - 0.96/paper - 22% HARD. Two broad subtopics, both routine coordinate geometry. Section Formula, Concurrency and Foot of Perpendicular (27 q) is 19% HARD and shares its whole toolkit with Line and Plane, so it costs almost nothing on top of a cornerstone you already own.

93 q - 2.08/paper - 56% HARD. The hardest chapter in the subject by rate, and unusually it does NOT cherry-pick: both its subtopics sit above 54% HARD. Continuity at a Point (47 q) is parameter-hunting; Limit Evaluation (46 q) is technique recognition.

90 q - 2.08/paper - 49% HARD. Dominated by Properties of Triangles (52 q, sine, cosine and projection rules). Note the taxonomy overlap: this chapter carries an Inverse Trigonometry subtopic (21 q) that duplicates the standalone Inverse Trigonometric Functions chapter - drill both or you will miss half the inverse-trig questions.

73 q - 2.04/paper - 37% HARD. A single-subtopic chapter, so there is nothing to cherry-pick: it is one 73-question block of identities, equations, principal values and sums. Its weightage has RISEN (1.66 lifetime to 2.04 recent).

99 q - 1.85/paper - 37% HARD. Trig Identities, Compound Angle and Equations is 77 of its 99 questions. Weightage has FALLEN (2.20 lifetime to 1.85 recent), the largest decline of any live chapter.

73 q - 1.85/paper - 45% HARD. Two subtopics. Symmetry, King's Property and Absolute Value (42 q, 38% HARD) is the one to own: those questions collapse in a line once you spot the property, which is the highest-leverage recognition in the calculus block.

50 q - 1.12/paper - 48% HARD. Small and expensive. Adjoint, Determinant and the A adj(A) identity is 14 q at 64% HARD. The compensation is that its identities are memorisable and reusable, unlike most of the long tail.

47 q - 1.04/paper - 38% HARD. Tangent, Locus and Equation Construction is 27 of its 47 q. Two Circles (tangency, common tangents) is only 9 q but 56% HARD, the chapter's expensive corner.

46 q - 1.00/paper - 33% HARD. Splits cleanly in two. Modulus, Argument and Polar Form (22 q) runs 18% HARD and is the half worth owning; Algebraic Equations, Locus and Cube Roots (24 q) is 46%.

47 q - 1.00/paper - 36% HARD. Effectively one subtopic: Area Bounded by Curves, Axes, and Lines is 43 of its 47 q. A single, well-defined skill, which makes it a cheaper page than its HARD rate suggests.

45 q - 1.00/paper - 40% HARD. A closed, formula-driven chapter. Every question reduces to reading a, h and b out of a combined equation and applying one of a short list of conditions, which makes it more learnable than its 40% suggests.

43 q - 1.00/paper - 42% HARD. The least mechanical chapter on the paper: no formula rescues a misread constraint. Selection and Arrangement with Constraints is 33 of its 43 q. One question a paper, and the one most likely to eat five minutes.
