First, go to the website of the school that is going to apply for the exam to inquire about the relevant enrollment and professional information, and then learn relevant experience from the brothers and sisters who have already passed the exam. If you don't know anyone, just call the admissions office for advice.
The tutor's words are more troublesome. If you know someone, you can ask him to introduce you. If you don't know, you can check the contact information of the tutor through the website or school, write or call, and it is best not to send an email. You can go directly to the school to find him if you need it.
