Should I take a preparation course?
If you are worried you won’t meet the entry requirements, there are IELTS centres and language schools around the world that offer preparation courses. You don’t have to attend one, but many students find it helpful.
Spend time with native English speakers
If you can, there's no better way to help with test preparation. There are services where you can chat online with a native speaker and practise your skills before the test. If this isn’t possible, try English YouTubers, podcasters, and TV to surround yourself with native speakers.
With a little preparation and understanding of what the requirements are, anyone should be able to master their entry requirement test.
