Wacker Dr, Illinois - US

I took my GMAT today, for the fourth time :D, and without doubt, this test center was the best so far.
Since I never seen the test center nor the building where it is located, I arrived 1 hour before the scheduled time. The personnel was very friendly and understanding. I was allowed to take the exam before the scheduled time. Toilets are really close, so does not require a lot of time to get there (for at ex. test center on Adams St. - Chicago - toilets are bit far, and hard to find - 8 minutes is kind of not enough if you want to go to the toilet and eat smth during the break).

Signed and scanned my palm and was ready for the fight.
The test center has 2 rooms. The one in which I was had 10 computers, each separated in a cubicle. I was given headphones / noise cancellation devices / 2 markers and 1 scratch pad.

One of the drawbacks though - if you finish a section ahead of time, even if you CAN take longer breaks, you will not be allowed to!!!
I finished my quant section 25 minutes ahead of time!!! and to my surprise, when I asked to use my break + time remained (I really did not need 33 minutes of break), the person who was monitoring everything clicked smth on the screen and bam - to my shock i had only 8 minutes of break.
Same thing happened after IR - I had 8 minutes left...and of course..i could not use any extra time for the break...

overall, i would give 4.5/5 to this center.
