Organise what you say
In the Cambridge First candidates should be able to use basic tenses as well as organise their ideas. As well that this it is a good place to include linking expressions in your ideas. Expressions and words like however, although, as well as and more can help you present much better answers to questions. See the box below for an example
More is better
When the examiner asks your opinion try to respond in detail. Look at these answers to a Part 4 question.
Some people say it is a waste of time to go to the gym and that you can exercise outside for free? What do you think?
Yes I think this is true. It is better to be outside with friends, going walking, playing football and enjoying the nature.
Yes I think this is true because being outside is better for you. For example you can spend more time with friends and do things like going walking or playing sports. As well as this, you can spend more time in the nature and in the fresh air. Personally, this is what I enjoy more as I think it gives you more freedom.
While some of the language in the answers is quite simple, in the first answer the information is very limited. You can see clearly in Answer 2 that the candidate tries to expand on their ideas and give more details. So this answer is much better-organised with a good number of linking words and examples to support their opinion.
Justify your opinions
From the example above you can see that you should try to add more information to your opinions. You don’t always need to think of great ideas,just remember the examiner is listening to your English and how you answer so always try to explain these ideas as best as you can.
