The Advanced Information from the exam board gives us a broad overview of
what is covered in the exam. The information was given in ranked order, and
this has been reflected in the mark allocation and topics on this paper.
There are questions in this paper that cover topics that are not listed by the
exam board. These are in the multiple-choice section and a few marks in low
tariff and synoptic questions – this is exactly what you should expect in the
exam.
