, MARK SCHEME – A-LEVEL COMPUTER SCIENCE – 7517/2 – JUNE 2021



Mark 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 the standardisation 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 the standardisation 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 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 avoided; whilst the guiding principles of assessment remain constant, details will
change, depending on the content of a particular examinationpaper.
