Courses

Courses that follow your syllabus, lesson by lesson.

Each course is built against its exam board’s specification and broken into short lessons — notes to read, flashcards to drill, and an assessment that marks you before you move on.

Notes

Notes written to be understood, not skimmed.

Lessons are laid out the way a good teacher sets out a board: definitions, worked examples, formula cards, data tables and step-by-step timelines, with the maths properly typeset.

  • Typeset equations, tables and diagrams — never a blurry screenshot
  • Coloured callouts for definitions, exam tips and common mistakes
  • A notepad beside the lesson for your own working, typed or handwritten
Flashcards & assessment

Check it stuck before you move on.

Every lesson ends with a flashcard deck and an assessment. Answer on screen, get marked straight away, and open the solution whenever you want to see how it is done.

  • Flip, drag or key through the deck — whichever is fastest for you
  • Assessment questions use the same answer types as the question bank
  • The solution and the grading criteria sit on every question

Inside every course

Mapped to the specification

Topics are ordered and named the way your exam board sets them out, so you always know where you are in the syllabus.

Four ways into a lesson

Notes, Flashcards, Assessment and — where a lesson has one — Video, as tabs on the same page.

Interactives where they help

Chapters link straight to the simulations that make their ideas visible.

Progress you can see

Each course shows how far through it you are, lesson by lesson, and picks up where you stopped.

Ask AI on the page

Light or dark

The whole product — notes, maths and diagrams included — works in both.
