The comments that already exist document the methods and their intended purpose, but of course none of them communicate the reason behind your design. You should include comments (typically inside the methods) that communicate reason as described in the Monday revision lecture. There should be some connection between the purpose and how you implemented it. Do not just repeat your implementation in English.
