How should you prepare for IELTS writing task 2?
Well, there is an enormous amount of advice. Here is a summary of what I suggest:

- Spend more time preparing than testing
When you test yourself, you find out what your level is, but you do not learn anything new. You will not improve if you only write test essays. Before writing an essay, study the topic and prepare your ideas, opinions and vocabulary.

- Copy my ideas
If you only use the vocabulary that you already know, you will not learn anything new, and you will not improve. Practice linking my topic ideas together to write perfect essays.

You need good ideas in order to answer the question well.

How to use these ideas to form a paragraph

It’s always recommended planning ideas for their main body paragraphs before starting to write. Let's look at how to put some ideas together to make a paragraph. Here's the question:

The main reason people go to work is to earn money. To what extent do you agree or disagree?

Ideas for one main paragraph:
·         Agree that money is the main reason people work
·         People look at salary first, they rarely take a salary cut
·         Need to live, pay bills, food etc.
·         Look after our families, save for the future
·         Otherwise, most people would probably choose not to work

Full paragraph using the ideas above:
I agree that the majority of people work in order to earn money. Before taking any other factors into account, it is normal to first consider the salary that a particular post offers, and it is rare to hear of a person who happily takes a cut in pay when beginning a new job. We all need money to pay for our basic necessities, such as accommodation, bills and food. Many adults also have families who depend on the wages they earn, and at the same time they are conscious of the need to save for the future. If we no longer needed money, I doubt most of us would choose to continue in our jobs.
