This is possible. I passed the examination of Grade II water conservancy constructor on 20 16 and 17, and passed the examination of Grade I cost engineer on 17 and 18. I'm going to pass the first-level construction in 2020. Passing these 2-3 years of exams is also a summary of learning methods. Prepare in advance and make good plans. The second construction examination is usually held at the end of May or early June, so the review time should be 2-3 months in advance, not too long in advance, otherwise the reading time will be too long, and the front line in May-June will be exhausted and upset, so it is best to prepare 2-3 months in advance. The second construction project is divided into three subjects: management, regulations and practice, and passed in two years. Therefore, some people who are not busy with their work can plan to pass within one year, and those who are busy with less time can pass within two years. This is the master plan.
