When preparing solutions for marking please note the following points.

- Not attempting a solution is generally unacceptable.
- Set out your solution as a coherent narrative explaining any principles used. The final solution should be underlined, or a reasonable gap left in the text so the end of the question is obvious.
- In general solve problems algebraically before inserting values.
- In multiple part questions, identify all the answers being asked for and present a solution that answers them all. Counting the things asked for in a problem, and matching this to the number of underlined results in your manuscript, can ensure this.
- Do not use different notation from that used in the question. Define any new variables you introduce.
- Write legibly. If you struggle to do this in first draft then rewrite your solutions when complete.
- Solutions should be presented on 1 side of the paper and stapled at the top left hand corner (or otherwise held together).

Obeying these rules is good practice and will pay off in exams. Scripts that fail to respect these rules will be returned to be rewritten.
