You ask first, those who can study in Aachen University of Technology and graduate smoothly are from those universities in China, and most people dare not challenge that university. It is true that you can graduate as long as you study hard. You have to see who said this sentence. Whether you take the Tsinghua exam or the junior college exam, it is said that you can get in by studying hard. Do you think this meaning can be the same, because everyone is not at the same level. I can only tell you that as far as I know, Aachen has a professional killer course, and there are two or three hundred people who failed the exam. Do you think these people don't work hard? Even if the passing rate of the general exam is 30% to 50%, you should be thankful for the high passing rate. Germans or students from other countries will not be more stupid and lazy than us. On the contrary, when you go to college, you will find that we are different from others, especially our practical ability and communication ability, which are very important to our personal ability. There are many excellent students in Germany. Except for their excellent exam results, they all got 1 in all subjects, and they also did well in other subjects. They usually work as substitute teachers at school to earn money, so they are perfect as students. At least, as far as my classmates in China are concerned, they rarely can do this. Put your mind right, there are excellent people there regardless of nationality.
