The staff have always been professional and friendly when I have been in attendance. They always explain the rules before entering the testing room. Unfortunately the test room has been a little on the warm side when I have been in there (I have done exams here twice between November and February and it was warm both times). They have some fans in there to try to keep things cool but I would recommend wearing a sweatshirt that is easy to remove for that reason. You get a small locker for your items and a key with a tag on it that dictates what kind of activities you are allowed to partake in (leaving for breaks, restrictions for breaks, etc). I am not sure every exam requires this, but be prepared to be waved over with a security wand and asked to pull up sleeves on shirts and legs on pants, empty pockets, and have jewelry/hairties examined to ensure you don't have anything that could be used to cheat. Overall, a good testing center
