, MARK SCHEME A-LEVEL CHEMISTRY 7405/2 JUNE 2020
Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant
questions, by a panel of subject teachers. This mark scheme includes any amendments made at the
standardisation events which all associates participate in and is the scheme which was used by them in
responses to questions and that every associate understands and applies it in the same correct way.
As preparation for standardisati
answers not already covered by the mark scheme are discussed and legislated for. If, after the
standardisation process, associates encounter unusual answers which have not been raised they are
required to refer these to the Lead Examiner.
It must be stressed that a mark scheme is a working document, in many cases further developed and
assessment remain constant, details will change, depending on the content of a particular examination
paper.
