Not bad. Its home is the institution put on record by the Education Bureau. It's a formal institution. At that time, I also checked before signing up. Its home is recorded in Xue Xin. That's why I feel at ease to upgrade my education in his home. Indeed, the teacher is very clear about the key points and has passed all the key exams in learning, so our scores are not low. Many students have applied for degree certificates. I think its home is still ok.
