Some of the staff can use some additional training!! For example, I saw a tall, thin, middle aged, male proctor hit a guy in the face with his metal detector when he was checking in after a break mid-test, and he somehow laughed it off and blamed the guy for leaning forward?!
Also, he served THREE people who had not even checked into their exams yet before clearing me to go back into my exam during one of my limited (and timed) break times! Outrageous! I spent several minutes of my limited break time watching him turn a computer on for another candidate. Also when he was checking me in at the start of the day he was so rushed I basically had to shove all my stuff into the tiny locker they provided and forgot to take my foam ear plugs out in the process.
However, all of the other staff were courteous and generally professional. Otherwise a generally worthwhile experience, with pretty standard protocols.
