The 14-hour study sessions were over but the nerves remained for Tong Dan as she squeezed in some last-minute cramming during a lunch break Monday from the most important test she and millions of other Chinese teens will ever take.
Each year, about 10 million high school seniors across China take the "gaokao" -- the exam that is the sole determinant for whether they get into a university. About 68 percent of test takers this year are expected to pass -- but for the vast majority who don't it means they head straight into the search for a low-paying, blue-collar job.
But even a college degree no longer guarantees graduates a good job in China's increasingly competitive workplace. With about 700,000 of last year's university graduates still unemployed, there is added pressure on students like 17-year-old Tong to do well on the two-day college entrance exam and gain one of the few coveted slots at the country's elite schools.
China has poured billions of dollars into a massive university expansion plan over the past few decades, meaning the number of graduates will skyrocket to a record 6.3 million this year, compared to 1 million in 1998. The expansion has also led to a widening gap between the quality of education found in many universities, especially those in poorer provinces, and the top schools.
