I have an IELTS in two weeks, what tips can you give me?

I'm soooooooooo nervous about speaking and time management on writing😭😭😭. I need at least 6 band, I'm actually pretty sure about my listening and reading, but some of my friends who passed an IELTS recently, told me that reading is very hard now, so I'm a little bit nervous about it too. Actually I love writing, like I can very easily get into flow state, but I overthink too much on both speaking and writing sections, so that I write too slow. Also I'm a little bit inteovert, but rarely when I feel good or something like this I can pass speaking section well, idk what is the reason for that. In my prediction: listening-7, reading-6.5, speaking 6 (I hope so), writing 6, and overall 6.5. Please give me some tips to improve my time management and nervousness on speaking😭😭🙏🙏
