How will the examiner deal with the fact that examinable documents are adopted at different times in different countries?
The questions and suggested solutions are altered to take this into account from paper to paper. The aim is always to ensure that papers are being set of consistent and comparable standard. If a candidate answers using the more recent version of the standard when the older version was examinable markers will take this into account when awarding marks and appropriate credit will be given. However, if according to the examinable documents a candidate should be using the most recent version but answers with an older version, markers will not give credit.
