Offering a multitude of examination services.
Ranging from professional to language tests or even university exams.

I've had exams where it gets really crowded, esp when you wait out side, you sometimes don't have anywhere to sit out side the examination room. (you can sit down stairs where they've set up tables for you to study , but it gets rather cold during winter if i remember correctly)

They've water vending machines, only allow you to bring in water, but you can get free water once you're in the examination room so I wouldn't burn my coins on slightly over priced water bottles.

Staff are quite professional, yet to have any problems with them. rooms are quiet and clean. I wish they could offer slightly more comfortable seating arrangements though.
