MARK SCHEMEA-LEVEL PHYSICS7408/1JUNE 20202Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevantquestions, by a panel of subject teachers.This mark scheme includes any amendments made at thestandardisation events which all associates participate in and is the scheme which was used by them inthis 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.Alternativeanswers not already covered by the mark scheme are discussed and legislated for.If, after thestandardisation process, associates encounter unusual answers which have not been raised they arerequired to refer these to the Lead Examiner.It must be stressed that a mark scheme is a working document, in many cases further developed andexpanded on the basis of students’ reactions to a particular paper.Assumptions about future markschemes on the basis of one year’s documentshould be avoided; whilst the guiding principles ofassessment remain constant, details will change, depending on the content of a particular examinationpaper.Further copies of this mark scheme are available from aqa.org.ukCopyright informationFor confidentiality purposes acknowledgements of third-party material are published in a separate booklet which is available for free download fromafter the live examination series.Copyright © 2020 AQA and its licensors.
