Next question

Simultaneous equations, a gentle one — you missed the last of this kind, so the same kind comes back with new numbers.

How it works

From the real exams to your next question.

We read the exams

We study the papers for your course, part by part: which skill each part tests, what it is worth, how the marks are given. That is how we know what your exam asks — and how it asks it.
We write new questions

Original questions in your paper's style, written from rules for each skill — never copied from a paper, and checked before they reach you: the answer, the marks, the working, the drawing.
Every answer is marked

Type it with a maths keyboard and see it as you type. Marks part by part, then the worked solution, the mark scheme and what went wrong.
It chooses what's next

An estimate for every skill, moved by each answer. A miss brings the same kind back with new numbers; a surprising one steps back to what it builds on; and it asks before moving you to a new topic.

A question from the bank.

Written by our generator for Extended Paper 2, no calculator — as you'd meet it in practice. Answer part (b), then see how every part is marked.

Cambridge IGCSE 0580 · 5 marks

Ria, Ugo and Cyrus share some sweets. Ria has $x$ sweets. Ugo has 3 fewer than twice as many as Ria. Cyrus has 5 fewer than Ria. Altogether there are 108 sweets.

(a)

Write an expression, in terms of $x$, for the total number of sweets, and form an equation.

[2]

(b)

Find $x$.

[2]

(c)

How many sweets does Ugo have?

[1]

How it's marked

(a) 2 marks

$x + (2 x - 3) + (x - 5) = 108$
$4 x - 8 = 108$

M1 for $2 x - 3$ and $x - 5$
A1 $4 x - 8 = 108$ oe

(b) 2 marks

$4x = 116$
$x = \frac{116}{4} = 29$

M1 for $4x = 116$
A1 $x = 29$

(c) 1 mark

$2(29) - 3 = 55$

B1 for 55, or follow through for $2 x - 3$ evaluated at their $x$

What you get

Everything a practice session should be.

Practise

Each question picked for you, from what you have unlocked. Keep a session for each way you practise, and one for a test coming: choose its topics and practise just those, with a bar that shows how ready you are.

Lessons

Read a lesson on a topic to unlock it, then practise it. Know it already? Take its quick check instead.

Progress you can read

Every topic of your syllabus, and every skill in it: Opening, Learning, Secure — moving after each answer.

How I practise

The exam's most-asked topics first, or one topic at a time. When to move on, what a wrong answer brings. Your choice, changed any time.

Worked solutions

Every question comes with its working written out step by step, and the mark scheme it is marked by.

Made for your phone

The question gets the screen; a keyboard with the maths keys each answer needs; light and dark.

Coming: worksheets to print, and exam-shaped papers to sit timed and have marked.

What we believe

Quiet, honest practice.

Original, never copied.: Real exam papers teach us what to ask. The questions you answer are our own.
Every mark explained.: Working written with each question — not a chatbot's guess.
Asked, not assumed.: It asks before moving you on, and what you've already been taught.
Calm, not a game.: A bar for each skill that moves with your answers, down as well as up. No points, no streaks, no characters.
Your practice is your own.: Use your progress to decide what to work on. Practice is a place to learn, including getting things wrong.

Free and paid

Start free, no account.

Anyone aged 13 or over can practise general maths for free, with no account (or try the question above). An account is for your own course: questions for your exam and level, and your progress kept.
