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 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 answers which have not been raised they are required to refer these to the Lead Examiner.  \nIt 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 examination paper.  \nFurther copies of this mark [scheme are available from aqa.org.uk](scheme are available from aqa.org.uk)  \nCopyright information  \nAQA retains the copyright on all its publications.

All rights reserved.  \nInformation to Examiners  \n1. General  \nThe mark scheme for each question shows:  \n• the marks available for each part of the question  \n• the total marks available for the question  \n• the typical answer or answers which are expected  \n• extra information to help the Examiner make his or her judgement  \n• the Assessment Objectives, level of demand and specification content that each question is intended to cover.  \nThe extra information is aligned to the appropriate answer in the left-hand part of the mark scheme and should only be applied to that item in the mark scheme.  \nAt the beginning of a part of a question a reminder may be given, for example: where consequential marking needs to be considered in a calculation; or the answer may be on the diagram or at a different place on the script.  \nIn general the right-hand side of the mark scheme is there to provide those extra details which confuse the main part of the mark scheme yet may be helpful in ensuring that marking is straightforward and consistent.  \n2. Emboldening and underlining  \n2.1 In a list of acceptable answers where more than one mark is available ‘any two from’ is used, with the number of marks emboldened. Each of the following bullet points is a  \npotential mark.  \n2.2 A bold and is used to indicate that both parts of the answer are required to award the mark.  \n2.3 Alternative answers acceptable for a mark are indicated by the use of or. Different terms in the mark scheme are shown by a / ; eg allow smooth / free movement.  \n2.4 Any wording that is underlined is essential for the marking point to be awarded.  \n3. Marking points  \n3.1 Marking of lists  \nThis applies to questions requiring a set number of responses, but for which students have provided extra responses. The general principle to be followed in such a situation is that ‘right + wrong = wrong’.  \nEach error / contradiction negates each correct response. So, if the number of error / contradictions equals or exceeds the number of marks available for the question, no marks can ","cbCaimaDbHz8Hf8l","https://ap.wps.com/l/cbCaimaDbHz8Hf8l","pdf",594491,"English","# Mark scheme information\n## How the mark scheme is prepared and standardised\n## Guidance to examiners\n## Emboldening and underlining\n## Marking points\n## Marking procedures and conventions","[{\"question\":\"Who prepares and validates the mark scheme used for the June 2020 exam?\",\"answer\":\"The mark scheme is prepared by the Lead Assessment Writer.
