How to choose a suitable remedial class mainly depends on the following aspects: 1. Whether the curriculum design is more professional and practical. The aviation and blog public examinations have always advocated small class teaching, so that candidates have more opportunities to communicate with teachers, and the comfortable classroom environment allows candidates to be more involved in their studies. If you teach in a big class, the teacher will leave you alone! 2. Whether the passing rate of students is high and true. If students only learn a lot of theories and some imaginary concepts and can't pass the exam smoothly, this kind of training center is not worth choosing. The passing rate of public aviation examination for three consecutive years is the guarantee of quality. Many candidates who are successfully admitted every year have participated in remedial classes for public examinations. 3. Whether the instructor has successful experience in the civil service examination.
