It's another heated day for the eight-hundred and forty thousand students that underwent the second day of the 2010 university entrance exam.The students are tested on three main subjects, with the test center saying that this year's math exam is less competitive than last year's. 　　All the test takers are barely surviving this hot examination day number two. The students are tested in English, Mandarin Chinese and Mathematics.Among the 690,000 students registered for the second group of the math testing, some are actually natural science test takers. If they do well in mathematics, it will provide them with a greater selection when it comes to choosing their majors. 　　According to the test center. the math exam this year is designed to be shorter and less complicated compared to last year's. It will allow students who are skilled in math to really prove themselves.
