The twenty topics.
Every one covers a single topic, and every question looks for a specific mistake — asked more than once, so you can tell a gap from a rush. All 20 come with the subscription: there is no topic to pick and nothing to buy separately.
Place Value & Rounding
Digits, zeros and rounding boundaries — where confident children lose their first marks.
Addition & Subtraction
Borrowing, missing digits and inverse thinking — the arithmetic slips that hide behind ‘careless’.
Multiplication & Division
Remainders, factors and sharing problems — including the remainder your child keeps throwing away.
Fractions
Of-the-rest problems, reverse fractions and bottom-heavy comparisons — the 11+ examiner’s favourite hunting ground.
Decimals
Place-shifts, decimal ordering and money chains — where one misplaced digit costs the whole question.
Percentages
Reverse percentages, increase-then-decrease and percentage-of-the-rest — the topic that separates top sets.
Ratio & Proportion
Sharing in a ratio, linked ratios and ratios that change — where one wrong part throws the whole answer.
Algebra & Sequences
Function machines, nth terms and think-of-a-number chains — where one jump too many costs the mark.
Measurement & Unit Conversion
Converting units and the factor-of-ten slips in between — where the unit IS the question.
Time & Timetables
Clock arithmetic, timetables and the 60-minute trap — plus Roman numerals, read and written.
Perimeter, Area & Volume
Compound shapes and the classic area–perimeter mix-up — where the unit carries the meaning.
Angles
Angles on lines, in triangles and around points — where 360° keeps being used in place of 180°.
2D & 3D Shapes
Properties, nets and counting the faces you cannot see.
Coordinates & Position
Plotting, reflecting and the missing corner of the shape.
Statistics & Data Handling
Reading charts precisely and the scale that isn't one-per-square.
Averages & Spread
Mean, median and mode — and finding the value that got away.
Money & Financial Reasoning
Change, budgeting and multi-step shopping chains.
Factors, Multiples & Primes
HCF, LCM and the number properties that hide in plain sight.
Probability
Fair and unfair games, and what 'likely' actually means.
Mixed Super-Selective Reasoning
The capstone: multi-topic puzzles at the toughest schools' level.
All 20, one price
There is nothing to choose between. Every topic, every worksheet and the whole dashboard come together — because you cannot know which topic to buy until you have sat one.
