Multiple choice questions

Multiple choice questions are perhaps the easiest to complete you simply put a cross in a box, however, the questions often have two answers that could, at first glance, be correct. Don’t make the mistake of reading the first answer and thinking this is correct without checking all the others.

If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes you will get zero marks. These multiple choice questions will not start with command words like ‘Describe...’ or ‘Explain...’. They will be written in the form of a question like ‘What...?’ or ‘Why...?’.

There will be more multiple choice questions on the Foundation paper.

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