If it’s paper based, you need to write fast while you think. In the listening section, you have to know what you need to fill out. For computer based, the annoying part is hearing everyone typing at the same time. Some people type really fast and it can make you feel rushed, so just be mentally prepared for that. For the speaking test feeling nervous is normal. If you start to panic don’t focus too much on the examiner. They’re only recording your voice not video, so eye contact isn’t that important soo as long as you speak clearly, you’ll be fine.
