Their teachers are all very powerful, including Zhao, a technical practice teacher, Gan, a comprehensive ability teacher, Lu, a case analysis teacher, and Wang, a standardized explanation teacher. I am a 0-based student and signed up for a worry-free class in early June. I really studied fire fighting for about 100 days because I took the first-class constructor exam from mid-August to September. Mainly look at the teacher's courseware, specifications, real questions and their own summary notes, and consolidate them repeatedly according to the notes. In the end, you can pass the exam as long as you get 60% right. There's no need to memorize difficult problems. Skipping won't work.
