If the agreement is signed, it will really bind the university. That's how I got here. I passed the independent enrollment of Tianjin University, and then signed an agreement: when I don't apply for the file, I will enroll and adjust my major to 30 points, and when I apply for the file, I will arrange my major 10 points. In other words, I can only go to other schools if I don't do well in the exam, drop 30 points and can't be admitted. Otherwise, no matter how high I get in the exam, I can only go to heaven. If you don't sign the agreement, it's useless to recruit yourself, which is equivalent to a white test. Of course, most provinces can tear up the agreement, as long as the university does not give you any trouble, because the agreement is legally binding, and it is illegal to tear up the agreement in a strict sense. Finally, candidates in Jiangsu can't tear up the agreement, and the Ministry of Education will help you put it on record, even if you want to tear it up. So you have to work hard to get into the exam, and then consider it comprehensively according to your usual exam level, the degree of preferential treatment you get and your own wishes. Be careful, otherwise the loss will outweigh the gain! For example, I didn't get into Tianda Investment Line, but I can still be admitted after dropping 30 points, so I can only enter Tianda, and it will arrange a bad major for me. It is better to go to a slightly worse school to study a good major.

Finally, good luck!
