Students are being forced to take additional exams to get into leading universities because good A-levels do not always indicate the brightest candidates. Sixth-formers applying to courses such as medicine and law are being asked to sit American-style aptitude（智能）tests, which are designed to assess（评价）thinking skills, among fears that too many A-level candidates are getting top grades. Last year, almost one in six students applying to universities such as Oxford and Cambridge from independent schools had to sit additional test to secure a place. Head teachers criticized the move, which they said would pile more pressure on schools and students. But universities insisted that the reforms were unavoidable, because A-level exams were no longer an accurate barometer（标准）of ability. In 1986, 40 percent of students starting at Oxford achieved straight. As at A-level, Mike Nicholson, its admissions director, said that this year almost every candidate offered a place would get perfect grades. It meant the university had to stage additional test to identify the most able candidates. “The ability to achieve three A grades is no longer the end-point in the admissions process,” he said. “The potential to achieved three A grades will allow them to enter the race for a place.” Oxford is not the only university turning to aptitude tests. At Cambridge, the number of students taking the university’s Thinking Skills Assessment shot up 26 percent to more than 3,000. A survey of 16,830 sixth formers applying to higher education from private schools last year showed that 2,860 had to sit at least one exam. Earlier this year, the National Foundation for Educational Research recommended that most sixth formers should sit SAT tests — a standard reasoning exam widely used in American colleges —to make it easier to pick out the best candidates. 5．What is the attitude of head teachers to the reform?
