What you are paying for
38,000+ phrases the mark scheme wants, highlighted in yellow
Every phrase an examiner has to see before they can give you the mark is picked out on the page, across all 1,175 pages. Learn the yellow and you have the answer in the words that score, not a paraphrase that nearly does.
The first ionisation energy is the energy needed to remove one mole of electrons from one mole of gaseous atoms to form one mole of gaseous 1+ ions.
Miss gaseous and the mark is gone, however well you understood it. Write “energy to remove an electron” and you score nothing. That is one definition out of 38,000 highlighted phrases.
And nothing else on the page
Every page is as short as it can be and still cover your whole syllabus. That is harder to write than a long one, and it is the difference between revising a topic and reading about it.
- No clutter, no waffle, nothing that wastes your time
- Your whole syllabus covered, and not one thing beyond it
- Higher Tier and Extended marked, so you never revise someone else's paper
- Cover a whole topic in one sitting, start to finish

Included, not an upsell
Every set of notes comes with its own flashcards and exam questions
19,000 of them, in 281 decks, one for every topic of every course. They are not written separately and they are not a summary: each card is built from the same highlights that are on the page, so the back of a card is the mark scheme’s wording and nothing else.
Then 2,500 exam questions, 368 sets, one for every topic, written in the style of the real paper with the mark scheme under each one. Every question is original, so you are not re-doing a past paper you have already seen.
That is the whole loop, and it is the part that decides a grade. The notes put the wording in front of you, the cards find out whether it stuck, and the questions make you write it out the way the paper will ask for it. All three are in the one price.
The cards and the questions for the free topics are free too, no account needed.

Where these come from
Built from marking, not from summarising
It is why the notes look the way they do. Yellow highlighting is exact mark scheme wording. Green is a method laid out in the order the marks are awarded. Red is a specific way students lose marks on that exact topic, taken from what examiners report going wrong.
