11+ VR — Cloze & word codes
Letter codes, anagrams, compound words — the Verbal Reasoning question types that show up most.
11+ VR — Synonyms & antonyms
Closest in meaning, opposite in meaning — vocabulary speed-drill for the verbal reasoning paper.
11+ NVR — Nets & 3D folding
Cube nets, paper folding, hidden shapes — the questions that throw most 10-year-olds off.
11+ NVR — Rotation & reflection
Mirror images, 90° / 180° / 270° turns, matrices — the spatial-reasoning core of every 11+ test.
11+ Maths — Word problems
Multi-step problems, working backwards, "find the missing number" — the questions that decide pass marks.
11+ Maths — Fractions & %

Quadratics
Factorise, complete the square, use the quadratic formula — the three GCSE methods drilled side by side.
Trigonometry
SOH-CAH-TOA, exact values, sine/cosine rule — the questions that decide a 6 from a 7.
Probability
Tree diagrams, Venn diagrams, conditional probability — examiner traps you fall into every paper.
Vectors
Column vectors, magnitude and direction, geometric proof — Higher-tier marks that look harder than they are.
Algebraic fractions
Simplifying, adding, multiplying and solving — the messy algebra that hides easy marks.
Ratio & proportion
Sharing in a ratio, direct and inverse proportion, exchange rates — applied questions in disguise.
Simultaneous equations
Linear and quadratic pairs — elimination, substitution and the graphical check.
Sequences & nth term
Linear, quadratic, geometric and Fibonacci — find the rule, find the term.
Biology Required Practicals
Osmosis, microscopy, food tests — the practical write-ups that examiners love to grill you on.
Genetic crosses
Punnett squares, dominant/recessive, sex-linked traits — the inheritance questions that keep coming back.
Electrolysis
Molten vs aqueous, anode vs cathode products, half-equations — full marks within reach.
Chemistry Required Practicals

Forces & Newton's Laws
F=ma, stopping distances, contact vs non-contact — Newton's three laws in exam dress.
Physics Required Practicals
Specific heat capacity, IV characteristics, density — every required practical drilled.
Genetic crosses (Combined Science)
Punnett squares + sex determination — Combined-Science tier with worked exam-style answers.
English Language Paper 1 Q5
Creative writing — the 40-mark question that decides your grade. Drill openings, structure and voice.
English Language Paper 2 Q4
Comparison question — drill the comparison connectives examiners want and the structural moves they reward.
Power & Conflict poetry

What is a booster?
10 hand-picked questions on a single tricky topic.
Every booster pulls 10 questions from our spec-grounded question bank, all on the same theme. You answer one at a time. The AI marks each answer in the way your real examiner would — point-by-point, with the exam-board phrasing the mark scheme rewards. At the end you get a score, confetti if you nailed it, and a path back into a sibling topic if you want to keep going.
