This document outlines the marking scheme for a DIRT exam, dividing responses into levels for each question. For question 1, higher levels require more depth, from surface details to main message and context. Question 2 evaluates identification and explanation of similarities/differences between sources, with higher levels providing more context. Question 3 examines explanation of a photograph's message with yes/no responses and context. Question 4 evaluates source usefulness based on content and context. The highest level for each question integrates purpose and context.
