Personally, I think the extra-long class is good. Generally speaking, the characteristic class will be more cost-effective. Because it is the same as the courses taught in the excellent class and the experimental class, the main difference is in the follow-up service. What are the specific follow-up services? You can check their website or call their customer service number to ask.

There are no textbooks yet, and Dongao doesn't sell them. They only sell their own counseling books. In any case, textbooks can only be published if they are registered. Not yet, but you can buy it at the local Xinhua Bookstore or the registration point.

I still think it's almost enough to buy a light four before the exam, that is, the last six sets of questions are done, and the intermediate level will be simpler than taking notes, hehe, good luck!
