MATHS Edexcel As Paper 1 pure answers 2023 GCE A level Mechanics (9MA0) – Paper 32 Mechanics October 2021 student-friendly mark scheme Please note that this mark scheme is not the one used by examiners for making scripts. It is intended more as a guide to good practice, indicating where marks are given for correct answers. As such, it doesn’t show follow-through marks (marks that are awarded despite errors being made) or special cases. It should also be noted that for many questions, there may be alternative methods of finding correct solutions that are not shown here – they will be covered in the formal mark scheme. This document is intended for guidance only and may differ significantly from the final mark scheme published in December 2021. Some questions require all working to be shown; in such questions, no marks will be given for an answer with no working (even if it is a correct answer). B1 – accuracy mark. This mark is usually given when working and the answer cannot easily be separated. A1 – accuracy mark. This mark is generally given for a correct answer following correct working. M1 – method mark. This mark is generally given for an appropriate method in the context of the question. This mark is given for showing your working and may be awarded even if working is incorrect.
