Hand-sorted from the legacy FP1 papers (2008-spec WJEC modular FM, 2005–2017) into seven narrow single-topic packs across the four examinable 2017-spec Unit 1 sub-topics (2.1.1 Induction, 2.1.2 Complex Numbers, 2.1.3 Matrices, 2.1.4 Algebra & Series). Induction is split into series-sum proofs vs the remainder (divisibility, recursive sequences, matrix powers); Matrices is split into $3{\times}3$ operations vs 2D transformations; Algebra & Series is split into Vieta’s relations (roots of polynomials) vs standard $\Sigma$-sums + method of differences. The new spec also lists Further Vectors (3-D lines, planes, scalar product, perpendicular distances — 2.1.5) and complex-number loci / w = f(z) transformations under 2.1.2, but FP1 contained no 3-D vector questions and zero loci work, so those sub-topics have no legacy practice and are covered in the crib sheets instead. The $3{\times}3$ matrices pack actually maps onto Unit 4 (2.4.3) in the 2017 spec — Unit 1 keeps $2{\times}2$ inverses + 2D/3D transformations — but the algebraic technique is identical, so this pack doubles as Unit 4 practice. 2D transformations (pack T5) was the sparsest legacy topic with only 2 questions across the whole FP1 corpus.

Hand-sorted from the legacy S2 and S3 papers (2008-spec WJEC modular FM, 2005–2017) into five narrow single-topic packs across the two examinable 2017-spec Unit 2 sub-topics (2.2.1 Random Variables / Poisson / Continuous RVs, 2.2.2 Regression / Correlation / Chi-Squared). The old "Random Variables & Linear Combinations" pack is split into discrete RV + sampling-distribution work (T1, from S3) versus pure linear-combinations problems on $U = XY$ (T2, from S2). Poisson (T3) and Continuous Uniform RVs (T4) keep their corpus but get tighter names. Linear Regression (T5) stands alone. The new-spec exponential distribution (2.2.1) had no legacy assessment in S2 / S3 and is documented in the T4 crib sheet only. Likewise, the new-spec Pearson product-moment, Spearman rank correlation, and chi-squared goodness-of-fit / contingency-table tests (all under 2.2.2) had zero questions in the legacy S3 corpus and are covered in the T5 crib sheet only — no separate question pack exists for them yet.

Hand-sorted from the legacy M2 and M3 papers (2008-spec WJEC modular FM, 2005–2017) and split into six narrow single-topic packs. 2017 spec 2.3.1 restricts momentum & impulse to the one-dimensional case — oblique / two-dimensional collisions live in the optional Unit 6 (2.6.2), not here. Topic 2 (Work, Energy & Power) covers KE / GPE / EPE conservation; Topic 3 isolates the pure Hooke’s-law statics (modulus calc and EPE at rest). Circular motion (2.3.3) splits into Topic 4 (horizontal circle, conical pendulum, banked tracks) and Topic 5 (vertical circles — complete-revolution conditions for strings vs rods, sphere problems). Topic 6 covers 2.3.4 (differentiation and integration of vectors in 2-D and 3-D, including relative motion and shortest-distance problems). Note: every legacy M2 W/E/P question is tied to elastic strings — pure W/E/P without elasticity is taught in Maths AS Unit 2.

Hand-sorted from the legacy FP1, FP2, FP3 and M3 papers (2008-spec WJEC modular FM, 2005–2017) onto the 2017-spec Unit 4 topics. Unit 4 is the 120-mark A2 paper worth 35% of the qualification, covering 2.4.1–2.4.8. 2.4.1 (De Moivre, e^{iθ}, nth roots) and 2.4.2 (further trigonometry, t-formula, sum-to-product) come from FP2. 2.4.3 (3×3 matrix inverses, simultaneous-equation systems, geometric interpretation) sources from FP1. 2.4.4 is split into two single-topic packs: T4 Maclaurin / Taylor series (FP3) and T5 further partial fractions (FP2). 2.4.5 (further calculus — improper integrals, volumes of revolution, inverse-trig integration), 2.4.6 (polar coordinates) and 2.4.7 (hyperbolic functions) span FP2 and FP3. 2.4.8 (differential equations — integrating factor, auxiliary equation, CF + PI, coupled 1st-order systems) is sourced from legacy M3 because legacy FP2 / FP3 contained no DE work; the spec excludes mechanics contexts, but the algebraic technique is the same and the practice transfers directly.

Hand-sorted from the legacy S2 and S3 papers (2008-spec WJEC modular FM, 2005–2017) into six narrow single-topic packs across the four examinable 2017-spec Unit 5 sub-topics (2.5.1–2.5.4). The old “Hypothesis Testing” pack is split into one-sample (T3, $z$- and $t$-tests on one mean) and two-sample / difference-of-means (T4). The old “Confidence Intervals & Estimation” pack is split into single-mean CIs (T5, normal and $t$) and large-sample CIs for proportions + difference of means (T6). T1 (2.5.1) keeps the merged sampling-distribution + unbiased-estimators content because every legacy S3 question is framed as “construct an unbiased estimator for parameter X using a sample” — the $\bar X$ sampling-distribution result and estimator theory are inseparable in the corpus. Mann-Whitney and Wilcoxon signed-rank tests are new in the 2017 spec and were not assessed in legacy S2 / S3, so they appear in the T3 crib sheet only. Correlation / regression / chi-squared sit in Unit 2 (2.2.2), not here.

Hand-sorted from the legacy M2 and M3 papers (2008-spec WJEC modular FM, 2005–2017) and split into six narrow single-topic packs. T1 covers 2.6.1 (rectilinear motion with variable forces — acceleration / velocity as a function of t, x or v). T2 covers 2.6.2 (vector momentum and impulse in two dimensions, including oblique collisions). T3 isolates moments, frameworks and rigid-body equilibrium (rods on pegs, hinged planks, non-uniform body COM via moments). T4 covers ladders + coplanar-force equilibrium (2.6.4). T5 is pure SHM (2.6.5 — amplitude, period, energy, spring-mass models), separated from T6, which holds the small set of 2nd-order linear DE questions (CF + PI technique, kitchen-scales damping model). Uniform-lamina COM questions (triangles, rectangles, semicircles) lived in legacy M1 which is not in this source set, so the rigid-body / lamina techniques sit in the T3 crib sheet rather than as a standalone pack. Variable-mass problems (rockets, raindrops) are absent from the legacy M2/M3 corpus.
