"The tipping culture. In Korea, after you eat at a restaurant, you do not leave extra tip for the waiters.
Smiling when you make eye contact with a stranger. In the US when you’re walking and you make eye contact with a stranger, smiling at them is not considered weird at all. However, if you smile at a stranger in Korea, they might think you’re weird."
So you can only take the exam once but if you don't pass you have to wait until the next year to take it again?
WTF?
In the US, at least in my state, you can take it 4 times and they take the best scores from each section and aggregate them into one score. So if you do well on Math on one test and well on Science on another test they combine them. We are getting dumber.
