How do you read a mark scheme for history?

For both A-Level and Gcse there are two steps. First of all, exam markers like myself use the table to determine the level. It starts with the higher number e.g level 4 and works down from there. You have to read each description and see which fits best. Secondly, we then determine the mark depending on how close you are to the next level. Hope that helps! Jess
