Enrolling in college in the United States remains a top goal of students at national high schools in major Chinese cities, according to a new poll  by Art & Science Group, which advises American colleges on enrollment strategies. The survey found that nearly all (94 percent) of students at these high schools are interested in college in an English-speaking country, and that 78 percent are interested in enrolling in the United States. Asked to rate the quality of colleges in the United States, Britain and Canada, the Chinese students gave the U.S. the best marks for academic quality, teaching critical thinking, the quality of facilities and prestige. Britain was on top in campus beauty and an emphasis on the liberal arts. (The scores were quite close for most categories.) Asked to identify challenges to study in the United States, 45 percent worried that they might not be academically prepared, 37 percent said that they didn't know enough about American colleges and universities, 28 percent said that they were concerned about their English skills, 25 percent worried about being far from home and 21 percent worried about whether their families could afford it.
