14) Teachers offer to "lend" students marks to pass tests
    Ananova [UK]

"A school in China is allowing students who don't do well in tests to
borrow a few extra marks as long as they pay them back with
interest. ... Students who do poorly on a test can ask their teachers
to lend them a few points to improve their grade, but twice as many
points must be paid back on the next test, assuming they achieve a
better mark. If they don't, interest on the loan continues to run at
100% per test until it is paid off." (02/02/04)
