It is fair in form, but there are differences. My friend Ben Shuo is from Nankai. He took the Tsinghua exam for two years and did well in the written exam. Finally, he failed. In the first year, people recruited their own master's degree, and in the second year, they did not want their own master's degree. Another student admitted to Nankai University was also the first in the written test in Tsinghua in the same year. A second-round exam participant came with a question, which is unparalleled. This guy was also brushed. So under normal circumstances, we have the opportunity to take the exam and interview, but the fairness of the interview can't be guaranteed compared with the written test, so it is very important to contact the tutor in advance and get approval.
Tsinghua's English is a little more difficult than CET-6, so you should be able to get real questions from Baidu. Just try it. I didn't take Tsinghua's exam. I don't have any information about it. My friend told me that it's a little harder than CET-6, but it's all 60+, so as long as there is targeted preparation, it's no problem to pass. Of course, the more exams, the better.
I wish you success ~
