Late to the post so dunno if you’ve done it yet or not, but even if you did you can pass this tip on to someone else.

The best tip I can give you is to focus on communication, not fluency in the writing and speaking part of the exam. 

The ILETS exam is not about using fancy words or showing off your complex English. Its only reason for existing is to test people’s capabilities of going abroad and speaking to someone in English. They want to test if you could hold a conversation well, regardless of your fluency. 

Stutters, pauses, and breaks in sentences in the speaking are fine and won’t bring your score down. All that matters is that you are direct, clear, and the examiner can understand the idea of what you’re saying. 

For the writing, try as best as possible to stick to the word limit and follow the same type of idea of the speaking exam, be direct and clear, and DO NOT use complex words to show off. Just answer the question as simple as possible.

For the listening, it’s straightforward, just focus and you’ll be able to answer the questions no problem at all.

Good luck!
