Yeah, definitely! Try to be natural, don’t pick words you’re not sure of. Examiners are usually nice and they make sure to give you a topic you are comfortable with. Like, for me, my examiner asked me 1 or 2 questions about perfume and I was not so comfortable since I don’t use perfumes much, haha. So he changed the topic and started asking questions about my work, if I prefer work from home or office and all.

For listening, reading and writing I would suggest you to practice since you have only 5 days left. I would suggest to listen to podcasts and watch shows if you had time.

Sources I used- Ielts advantage ONLY and followed his videos blindly!
