Each trial is a full mock examination. Every question breaks down into parts (a), (b), (c)… — work through them in order. Timer counts down; submit any time or wait for auto-submit at zero. Results show a per-topic breakdown.
A line on a grid has a gradient — a number that tells you how steep it is. We’ll work through four lines. The first two guide you step by step; the last two ask you to predict. By the end you’ll have worked out the gradient formula yourself.
Given two points, the midpoint is the point exactly halfway between them. We’ll work through four pairs — first two guide you, last two ask you to predict. By the end you’ll have worked out the formula yourself.
Most people think of interest as something you add to your balance. There’s a faster way to see it: as a multiplier. We’ll work through four accounts — the first two guide you step by step; the last two ask you to predict. By the end you’ll know why compound interest is exponential.
When you do two independent random things (like toss a coin and roll a die), how likely is a particular pair of outcomes? We’ll work through four scenarios — first two guide you step by step, last two ask you to predict.
Answers can be entered as fractions (e.g. 1/12) or decimals (e.g. 0.0833).
Solving an inequality is almost the same as solving an equation. Almost. There’s exactly one move where the rules change. We’ll work through four problems — first two guide you, last two ask you to predict. By the end you’ll have found the move.
A two-way table sorts a group two ways at once — dogs or not, cats or not. Every row sums to its row total; every column sums to its column total; those totals all add up to one grand total. When a cell is missing, you can always find it by subtraction. We’ll work through four tables — first two guide you, last two ask you to predict.
