Multiple choice questions

Multiple choice questions will appear throughout both exam papers, and at both Foundation tier and Higher tier.

These questions provide you with a number of answers, from which you must select the answer or answers that you think are correct.

The question may tell you in bold how many ticks, rings or lines to draw. If you draw less than this, or more than this, you will not be able to get full marks. Make sure that you draw straight lines rather than complex wavy lines.

There will usually be more options than correct answers. Don't just go for the first option that looks correct - read each option carefully and decide whether it is right or wrong.

These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.
