• A useful start is to make an exhaustive list of the conditions you will need to know about for the CASC. Using the ICD-10 as a guide is useful, but remember there may be conditions which are not in there (e.g. re-feeding syndrome) that can also come up.

• Once you have your list, for each condition you need to know the main symptoms, diagnostic criteria, prognosis and management. To make sense of the management, try writing the different aspects into a 3 × 3 grid, which splits it up into short, medium and long term, and then again into biological, psychological and social areas. This formulation of the management plan will feed into the structure you develop for presenting information in a station, making it much more manageable, concise and complete.

• For every commonly used drug you need to know doses, titrations, sideeffects and contraindications. If the drug requires special monitoring through plasma levels or other blood tests, you need to know these too.

• For every form of therapy you need to understand it enough to be able to explain it.

• Use a variety of sources for your revision (e.g. standard textbooks, evidence reviews, National Institute for Health and Care Excellence (NICE) guidelines, websites, patient information leaflets). We have put together a useful list of resources at the end of the book.
