It is suggested that the landlord join the construction engineer instead of buying genuine textbooks for the following reasons:
1, the original version is too expensive and the service in official website is poor;
2. The problem set of genuine textbooks is simply redundant, and the quality of the problems is too poor. Compared with the test questions, the quality is too poor. Doing problem sets will not only fail to learn, but also mislead you.
According to my personal experience, the textbooks will change in 20 13 years, because the Ministry of Construction issued many new specifications last year and this year, and the textbooks will change.
4, pirated textbooks can be bought without going out, Taobao, Dangdang more.
