More than 9 million students sat China's notoriously tough college entrance exams with "high-flyer" rooms, nannies and even intravenous drips among the tools being employed for success, and with just 6.85 million university spots on offer this year, competition for the top institutions is intense, and attempts to cheat are rife -- 1,500 people have been arrested on suspicion of selling transmitters and hard-to-detect ear pieces.
