Jennifer's advice is excellent. I've bookmarked her post for my own upcoming writing exam. The only thing I can add is a resource for more practice topics.
The ETS
PPST Writing Test-at-a-Glance PDF includes 71 essay prompts. Some (but not all) of the prompts are education-related, but the PDF is FREE.
The best way to prepare for writing an essay under pressure is to practice writing essays under pressure. I spend half an hour every Sunday practicing (with a timer!) This practice has been extremely valuable in learning to quickly outline my thoughts and to pace myself instead of wasting time waiting for inspiration to strike.
Good luck to you!
