Comment on I've found this article about enrolling as a foreign student, and I'm concerned.
Why are you using a private service to handle your admittance? You're better off contacting people at the Confucius Institute and try to get a scholarship through them (you have to be under 25). You're from Europe so it's a different story. There is a quota per nationality for scholarships, and thus as someone who isn't from the global south, it will be easier to get in.
If you're interested in studying in China; start studying Chinese. While your Chinese will improve a lot more rapidly when in China it is still a difficult language that requires you to invest a lot of time and effort.
It would help if you told us what kind of program you're interested in. Do you want to study sinology? Do you want to study engineering? What is your goal? Depending on the type of direction you want to go you might need an entirely different scholarship.
