The requirement of IELTS for most majors in the Chinese University of Hong Kong is 6.5, while TOEFL is only 80. For engineering students, if your English level is average, it should be more appropriate to choose TOEFL. The reason is that the Hong Kong University of Science and Technology requires IELTS 6.0, with a single item of not less than 5.5 and TOEFL 80. Many engineering students failed to break their legs in IELTS speaking and composition, and either scored 5 points or scored 5 points in one of them, which affected the application progress. TOEFL score of 80 is far easier than 6 and not less than 5.5.
