The exam is in two parts; the first an English comprehension test (one Korean guy was totally upset because he couldn’t read/understand English and also had a very poor command of it as well) and the second part is looking at color x-ray images of banned object in suitcases. You have fifteen seconds to click a ‘yes’ or a ‘no’ ....
Oh my, standards have slipped a bit in the last 10 years :-(
