taking my driving test

So I am 17yo and will be taking my test on the 7th coming up and I am really nervous. I will be at the dps office in humble. Will a go on a specific route? Or is it just randomly "turn here" "turn there"? I have my permit already and I have been practicing my parallel parking and I actually can do it without stressing about it 😅. But seriously, how could I not be as nervous about this?
