448 yuan has a tutor to answer questions at any time. The voice answer is valid until you understand it. The whole process of answering questions and counseling, the whole process of supervising learning, the counseling package passed, and the class was reported. It is recommended to choose online school to study at any time. Teachers can answer questions one-on-one at any time, escort you and use fragmented time to study. You can not only attend classes, but also receive one-on-one counseling and answering questions. There are many face-to-face lectures now, and the fish and dragons are mixed. If you are lucky, you won't have to pay for this course for nothing. If you are not good, you have to pay for water and waves. In addition, it is difficult to attend classes on the spot. If you don't understand, you will pass. If you can't keep up step by step, the teacher will leave after class. It's almost impossible to ask questions. Online training is different. Review in three rounds:

The first round focuses on the basic knowledge of various subjects.

The second round, crazy to do the problem.

In the third round, leave a week to check for leaks.

The first round is mainly to master knowledge and cram more knowledge points into your mind. In the second round, I sorted out the knowledge points, and finally I was in full swing. In the third round, I prepared for the exam.
