If you think the SAT tests are tough, don't bother applying to the University of Al
Azhar in Cairo, Egypt. Though the ancient school has been graduating students for more
than a thousand years, the qualifying exam is far more challenging than any devised by the
Educational Testing Service. Each year, every incoming freshman is required to recite the
entire Koran from memory. The text of this Islamic holy book is nearly as long as the New
Testament and takes three days to repeat. But every one of Al Azhar's 20,000 students has
passed the test.
