Pick quotes that can be reused across multiple themes — for example, 'love your neighbour as yourself' works for relationships, peace and justice. For each quote, learn the exact wording, the source (book or thinker), and two themes you can apply it to. Short powerful quotes score as well as long ones, so do not waste memory on a twenty-word passage.

Use a clear four-part structure. One: state one side of the argument with a religious teaching or quote. Two: develop it with explanation and reasoning. Three: give the opposing view, ideally from another religion or a non-religious perspective like humanism. Four: reach a justified conclusion saying which side is stronger and why. Always refer to the statement in the question. Aim for 300 to 400 words and use the phrase 'on the other hand' at least once.

It gives you an automatic counterpoint in evaluation questions and shows you understand that moral reasoning does not only come from religion.
