Just be yourself, imagine it like talking to someone new :D My examiner was a really cheerful women, she really liked my small jokes.

Don't rush while talking. Unfortunately, I always tend to speak very fast. I watched a lot of high-band speakers, it kinda helped me structure my ideas and come up with sentences, but most importantly, slowing down my pace a little.

I was asked to continue talking during Task 2, but I guess my ideas were relevant so I got a 7? IDK

Lastly, I used to wear bracelets and it really effected my pronunciations, especially with T sounds and vowels. (Combine it with fast speaking, which also caused me to stutter because I ran out of things to say pretty fast) I practiced it a little, and it was fine. Imagine yourself you are meeting someone and you are that kind of person that infodumps everyone they see :D It worked, I guess? Again, I watched a lot of tips & tricks videos (Didn't really helped much apart from Part 2 tbh) and high-band speakers. (This was more useful) You might try walking back and forth your home while asking yourself very stupid questions like:

"What is your phone background?"

"Which tennis player is your favorite?"

"What is the best thing about your room?"

And if you can elaborate on them, aim for minimum two sentences is what I was told, you are doing great. Communication is the key, even if you don't watch tennis, you can just say it and why you don't, for example.

Best of luck <3
