Students tend to worry about 'difficult questions', but questions are often much easier than they seem. For example:
Describe a law in your country.
Many students think they don't know anything about laws. However, there are some easy examples that they could choose:
- In many countries it is now illegal to use a mobile phone while driving. You could start by talking about the popularity and benefits of mobile phones, and explain that people want to be able to answer calls wherever they are. Then you could explain the dangers of being distracted while driving; this law could reduce the number of road accidents, and therefore save lives.
- If you feel confident talking about the 'education' topic, you could choose the 'compulsory education' law. This is the legal requirement that children up to a certain age must attend school. In the UK, for example, children are required by law to continue in education until they are 16 years old. This is a good topic because you can talk about the benefits of education.
Of course, you could choose a more obvious law (it is illegal to steal, carry a gun etc.) but you might have more ideas and good vocabulary if you choose a typical IELTS topic like number 2 above.
