I had a very pleasant experience here. Nothing to complain about, for sure. Staff was extremely friendly and promptly answered my questions. I didn't have any issues during my test, either. The only thing I will say is that I was bothered that online it says I could bring a light sweatshirt in but once I arrived I was told I could only wear a pullover (I had a zip-up). The room wasn't necessarily cold, but once the A/C kicked on it got cold at times. Otherwise the room was clean, the testing stations were clean and organized, the chairs were moderately comfortable (I had a 6 hour test), the headphones had covers on them to keep them clean, and I never had to wait long once I raised my hand when I needed something.
I hope I don't have to retake the exam I did, but if I do I wouldn't mind returning here.
