One-mark questions

One-mark questions often ask you to state, predict, or give a simple reason to explain something. You do not have to answer in a full sentence, but it is usually a good idea to do so, in case that helps to give your answer more depth which might help you to score the mark. Make sure that you include key words in your answer, as these are often required by the mark scheme.

Foundation tier papers may include questions in which you have to draw lines to match correct options. These questions will include distractors, which are incorrect choices.

When you answer a line matching question, use straight lines. Draw the number of lines needed to answer the question.
