For IELTS reading, make sure you calm down during the exam and practice. There are some basic rules for true, false, and not given questions. First, don't make an assumption about what has been illustrated in the passage. If the answer is true, it's usually clear from the passage. However, there is a thin line between false and not given. Try to get hard copies of IELTS reading materials, this will help you to trace answers with pen or pencils. Thank you
