Because of the tuition,
Or because your parents don't think the school you want to take is very good,
Even because your parents' ideas conflict with yours and so on.
Find the main contradiction, and then prescribe the right medicine-
If it is because of tuition, you can get the required tuition through labor, or the national student loan;
If parents think the school is not good, it is only in its infancy. Maybe failing in the college entrance examination can only mean failing in the college entrance examination, but people can survive.
If you say that your parents are in conflict with your ideas, or that you have little confidence in getting into the exam, then you should work hard and let your parents see your efforts. Your parents will definitely support you when they see your efforts. After all, parents have the same heart for their children, and they all want their children to be self-motivated and have a good life, provided that you are determined to take the exam and work hard, let alone work hard.
I hope my answer will inspire and help you, and I wish you success in your studies!
