Germany often emphasize on honesty, you can not say "yes" if there is "no", otherwise, everything is turned out worse. There is a big problem: examine the qualifications to study in German. There are some students to study to German with false educational certification, there is something wrong with the students as well as agencies. The actual age of some students is less than 18-year-old, who have had diploma. Although these students live in Germany, they do not have certification which is authorized by German embassy in China. They also do not dare to come back to check, since the students who do not have the examine proof are not allowed to enter into the German free public universities, those worry about for this all day and foreign travel. So it is advertisement that those who do not have true certification cancel going to German plan.
