Building a model answer

A model answer is not one long paragraph. It is a set of mark-sized pieces.

Step 1: copy the named item from the question. For HTML this might be a file name, URL or page title. For Greenfoot it might be a world name, actor class, object count or save name.

Step 2: write the syntax that uses that item. For HTML, that means tags and attributes. For Greenfoot, that means constructor code, act methods, collision checks, sound calls and counter updates.

Step 3: check the mark scheme pattern. If the paper asks for 13 marks, expect separate marks for population, movement, collision, sound, counter, score change and save name.

Step 4: compare your answer with the walkthrough. Anything in the model answer builder that is missing from your answer is a revision target.
