Hi Lara —
Here’s a link to a great post about the writing section —

My suggestion, if you are nervous at all about it, is to practice once or twice before test day, and you should be all good to go — you definitely don’t want to waste too much time and energy thinking about/preparing for it —
Hope that helps and if you have any follow-up just let me know —
Mike
