Every topic page, practice sheet and answer scheme lives here. Nothing on this site is meant to be read — it is meant to be attempted, marked, and returned to a week later.
Your marker sits on the band your banked marks put you in, across every topic you have opened.
Each finished page carries six lessons, an interactive tool, six videos with written tasks, and 15 questions worth 30 marks.
Paper versions, for when a screen is the wrong tool. No calculator unless the sheet says so.
One a week. Two minutes of thinking beats twenty minutes of reading — and every one of these is a question someone drops marks on in the real paper.
Four rules. They exist because the difference between 10 out of 15 and 13 out of 15 is almost never new knowledge.
Reading a worked solution feels exactly like understanding it. The only way to tell the difference is to have committed to an answer first, even a wrong one. A wrong answer you wrote down teaches you more than a right one you read.
A session is over when you have banked marks, not when the clock says so. Ten honest marks in twenty minutes is a good session. Forty minutes of scrolling is not a session at all.
Watching is passive; the task is the part that sticks. If you are not going to write the three lines underneath, close the video and go straight to the questions instead. That is a legitimate choice.
First pass finds out what you know. Second pass, a week later with the page reset, is the one that moves your score. Targets on each page are set in pairs for exactly this reason: 21 first, 26 second.
