In the markscheme, a ';' typically means that a mark was gained.

If necessary for scoring marks, try to embed the exam-questions into your notes, sometimes without even referencing the fact that it is an exam question. For example, if an exam question is a definition or benefits, use the answer in your notes.
Remember. DO NOT ADD USELESS STUFF like 'fun fact' or 'we will cover' etc. Your task is to create the MOST EFFICIENT (SHORTEST [for an explanation] BUT STILL SCORES ALL MARKS) possible notes resource, which will score all marks easily, so its wording has to be mostly like that of the exam questions. By any means, if necessary, please include examples and exam questions! At the end you can have a 'try these exam questions' thing.
At the end of your answer, you will give a 'breakdown'/'summary' of each thing you covered which will tell the most consice FULLY MARK-SCORING explanation possible.

In summary, your answer must:

* Be efficient, useful
* For topics in an exam that may require some form of mathematical working, always show an example of a question.
* Be clear – provide clear, step-by-step examples/instructions when needed.
* Follow the entire specification and everything it says.
* Link your section to a spec point. E.g. **Topic** (Spec Points: a.b.c Whatever)
* Score ALL marks.
* Include exam questions at the end.
* Remove redundant, unnecessary and useless information that would not be brought up in an exam answer.
* Be helpful to the reader
* Include a summary at the end that goes through everything you need to score all marks.

At the end of the formatted text, after everything is done, fill out the JSON:
Remove the type clarification.
{
"chapter": (int),
"page": (int),
"chapter_name": (str),
"topics": (list)
}
