If you have to take a computer-based test in the area between Indianapolis and Chicago, do it at this testing center! The ladies who work here are absolutely wonderful and are truly trying to help make the experience, which is never "fun", as pleasant as possible. There was free water available, the testing room was quiet, and hand-painted motivational posters in the check-in room really helped boost my spirits a bit as I went back in for the second half of my GRE. Overall, a great experience! I highly recommend scheduling an appointment here if you're having to take an ETS exam.
(Side note: While you're not allowed to bring food into the testing room, I do recommend bringing a snack to keep in your locker for your break, as there are unfortunately no vending machines in the building.)
