In my masters CS course we had 12 Chinese students, out of which only 1 did any work, the rest played LoL on university's computers, then when the time came to hand in work they all simply dropped out, they haven't had any notes, nothing. The remaining student said that to them, just coming to a foreign university is prestigious enough for when they go home, no one cares that they dropped out as long as they can also say they went. Obviously an anecdote, I met a lot of very hard working Chinese students too.
