First, communicate with parents. Since you are not interested in all the training courses your parents reported, you should explain to your parents, tell them how you feel, you don't like these training courses, and give them some suggestions on the training courses you like. Explain to them your hobbies, your future major, your ideals and goals, and tell them not to worry. You will try to make them feel at ease. I believe they will understand you.
Second, understand the pains of parents. Nowadays, the society is a society of talents, and the competition is becoming more and more fierce. The reason why your parents give you training courses is that you can become a talented person and have your own competitiveness, so that you can stand out in the future competition and win thousands of miles.
Third, strive to improve their academic performance. Your parents signed up for classes in the hope that your grades would make a qualitative leap. As long as you work hard and your grades go up, your parents won't sign up for this kind of training class to restrain you. So study hard from now on and let them see your progress, so your parents won't give you many training courses.
Actually, as an experienced person, I tell you that the things in the training class may not be as good as what you teach yourself, but it will certainly not harm you. The teachers in the training class are all experienced in counseling, and their experience can save you a lot of detours. Therefore, it is not bad to take more training courses in vulnerable subjects.
In fact, our study mainly depends on ourselves, communicate well with our parents, strive to satisfy our parents and create our own future.
