"Do you know Japan?" General Knowledge Quiz (by Chris Snuggs)
The idea is to learn something about Japan you didn't already know.
The best strategy is to do this test NOW, then tomorrow, then two days after that, four days after that and so on! Doing it ONCE only will not burn the key information into your memory banks!
Remember that many sets of statistics are approximations; it is for example impossible to know the EXACT number of people living in Japan at any given moment, but any estimations are nonetheless close enough to be useful.
