Cambridge IGCSETM

CHEMISTRY Paper 2 Multiple Choice (Extended) MARK SCHEME Maximum Mark: 40

0620/22 March 2021

Published

This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners' meeting before marking began, which would have considered the acceptability of alternative answers.

Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers.

Cambridge International will not enter into discussions about these mark schemes.

Cambridge International is publishing the mark schemes for the March 2021 series for most Cambridge IGCSETM, Cambridge International A and AS Level components and some Cambridge O Level components.
