You will obviously not follow exactly the same study plan, but it shows you that it is very easy to make improving your English part of your daily routine.

Learn From Your Mistakes

You should find out what your common mistakes or weaknesses are and then you can focus on improving them. Some people are very fluent speakers, but make lots of grammar mistakes, some people are very good at grammar, but speak at an unnaturally slow speed and others are difficult to understand because they need help with their pronunciation.
Find a good IELTS teacher either in your local area or online and ask them to tell you your weak points.
If you have a friend who is a native or advanced English speaker, they can also help you with this.
Finally, you should record yourself and this will help you spot your weaknesses and help you fix them.

Prepare For the IELTS Speaking Test by Listening and Reading

In order to do well in the speaking test you will need to improve your overall level of English. As stated above, you will be marked on your grammar and vocabulary, so improving these is essential. Listening and reading in English will really help you improve these skills.
For listening you should definitely check out Podcasts. Podcasts are like radio shows, but you can download them and listen to them whenever you like. There are millions of podcasts so it shouldn’t be difficult for you to find one you like. Try to find one on a topic that you are interested in, rather than one about learning English or IELTS.
For reading you should find a blog that interests you. All you have to do is Google a topic you’re interested in and type ‘blog’ in the search. For example, you might be interested in travel so just search for ‘Travel Blog’.
