yup...I wrote the DAT there on August 1st of this year.
I came a little early and they let me start right away. They give you a locker (big enough to fit a backpack) and key. The washrooms are located about 30 seconds away from the place.
Inside the testing room, there are about 20 cubicles with computers set up in two rows, if I recall correctly. They have headphones at each cubicle.
The temp. was perfect the day that I wrote it...and I'm usually very sensitive to temp. 🙂 so that was a plus.
Overall it was fairly quiet, lights weren't too bright...good ambience for test-writing.
