The entrance exam is still close to the college entrance examination, which is quite different from DSE. Of course, English is still simpler than DSE, so reading textbooks in the mainland should not be enough. You'd better have a special teacher to help you. Recommend the Chinese College of Jinan University, there is not so much pressure to get into a good university. If you are studying in a high school in the Mainland, you should go to a special training institution to familiarize yourself with the examination syllabus and questions. Different types of Hong Kong, Macao and Taiwan fresh candidates have different admission methods. Students from Hong Kong, Macao and Taiwan who have experience in studying in the Mainland will generally choose the joint recruitment of Hong Kong, Macao and Taiwan. This is the largest exam held by the state for all students from Hong Kong, Macao and Taiwan, and it is called "Joint Entrance Examination for Overseas Chinese and Hong Kong and Macao Students in Colleges and Universities". National joint recruitment of Hong Kong, Macao and Taiwan will generally become the first choice for students from Hong Kong, Macao and Taiwan who have studied in the Mainland, because the subjects of national joint recruitment have a high degree of overlap with the college entrance examination. Chinese, mathematics and English are compulsory, the scores of liberal arts excluding politics, geography and history are raised to 150, and the scores of science excluding biology, physics and chemistry are raised to 150, and all subjects add up to 750, which is the same as the college entrance examination.
If you want to know more about the joint entrance examination of Hong Kong, Macao and Taiwan, I recommend choosing the Chinese College of Jinan University. Chinese College of Jinan University, as a specialized college for training language talents, has two key points: teaching and scientific research. The student-oriented and ability-oriented quality control and effect evaluation mechanism, supported by strong scientific research strength, provides a strong guarantee for overseas Chinese education to move towards standardization and specialization, and also enriches the connotation of Chinese education disciplines and helps students learn without worry.
