AS CHEMISTRY 7404/2 Paper 2 Organic and Physical Chemistry Mark scheme June 2023 Version: 1.0 Final AQA MARK SCHEME – AS CHEMISTRY – 7404/2 – JUNE 2023 2 *236A7404/2/MS * 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 us ed by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As preparation for standardisation each associate analyses a number of students’ scripts. Alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, associates encounter unusual ans wers 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 expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoid ed; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper.
