TIPS for reading:
Look carefully at the instructions for each part. They will tell you what to do.
• Look at the titles of the longer texts. The titles will help you to understand what the text is about and where it comes from.
• Read the texts and the questions carefully, and make sure that you answer the questions. Don’t just choose an answer because you see one word.
• If you don’t know the meaning of a word, don’t worry. Try to guess what it means.
• Answer all the questions, even if you’re not sure. Always choose an answer for each multiple-choice question.
• Take your time and don’t hurry. There is plenty of time to answer all of the questions.
