Why the notes are different
Every page knows what the exam will ask.
Your notes already know the question. Every page tells you how the point is examined, how many marks it carries and what earns them, so you never spend an evening on something that will not be on the paper. That is hours back every week, and marks most students leave behind.
What is tested
Open any page and you see the exact shapes the question comes in, the command terms and the marks. No guessing what they will ask.
How it is marked
Every worked example is laid out the way marks are awarded, so the method you learn is the method that scores.
What to skip
If something rarely earns a mark, it is not on the page. Your hours go where the grade is, from the first week.
What you get
Built the way the exam is built.

Notes written by subject experts
