At the end of each section, you will find an opportunity to ‘Check your progress’. These questions have been carefully designed to help you to see how well you have understood and learned the topic. The answers are given at the end of the manual. You can choose to look at the answers before trying to complete the question yourself, if you want to. But the only person you will be cheating is yourself. No-one will take in your manual and mark it for you. You yourself must judge how well you are doing. You may also find some practical activities. You will need to collect the required equipment.
