Weak areas and programme links

Each diagnosed weak area is linked to the part of the catch-up programme designed to address it.

Index laws

high to address

Baseline Q24 blank (division of powers/exponent explanation).

Programme link: Priority 1 — Algebra & graphs (alg)

Parallel-line and polygon angle rules

high to address

Baseline Q17–18 blank (parallel-line rules); Q19 incorrect (used 360÷8 rather than polygon interior-angle sum).

Programme link: Priority 1 — Angles & polygons (ang)

Percentage decrease / reverse percentage / profit

high to address

Baseline Q15 blank (15% reduction). Percentage/fraction conversion Q14 and simple interest Q16 were secure, so the gap is percentage-change application rather than all percentage work.

Programme link: Priority 1 — Percentages, ratio & proportion (prp)

Rearranging formulae

high to address

Baseline Q5 blank (make x the subject).

Programme link: Priority 1 — Algebra & graphs (alg)

Straight-line equations / y=mx+c

high to address

Baseline Q9 blank (form equation from a table); Q8 gradient/intercept was secure, showing the gap is applying y=mx+c rather than recognising its parts.

Programme link: Priority 1 — Algebra & graphs (alg)

Substitution with negative numbers

high to address

Baseline Q2 incorrect (3a−2b with a=4, b=−2).

Programme link: Priority 1 — Algebra & graphs (alg)

Trapezium area

high to address

Baseline Q20 incorrect: calculated 144 cm² instead of 72 cm².

Programme link: Priority 2 — Measures & shape (mea)

Vectors / translations

high to address

Baseline Q23 blank (translation by vector).

Programme link: Priority 2 — Vectors & sequences (vec)

Circles, Pythagoras, standard form and probability

medium to address

Retained by the updated post-diagnostic gateway plan as confirmation/revision gaps; these were not all directly sampled in the 24-question answer export.

Programme link: Priority 1 — Circles, Pythagoras, standard form & probability (cir/pyt/std/pro)

Measures, statistics, sequences, units/binary/data and Python

medium to address

Retained by the updated post-diagnostic plan as Priority 2 correction areas after the readiness confirmation.

Programme link: Priority 2 — Remaining correction areas (mea/sta/vec/uni/pytc)

Ratio / unitary method / best buys

medium to address

Baseline Q11–12 secure; Q13 best-buy comparison blank. The targeted gap is unit-rate comparison.
