Erjian is the simplest and easiest exam among all the registration exams, with a high pass rate. If you work hard, you can get it. The institutions that built the second building are all fake, and the promises to build or protect them are deceptive. The national qualification rate of the second construction project is less than 15%. In this environment, "unconditional guarantee 100% pass" is unrealistic.

The second-level constructor exam is generally held in June every year, and each province will be slightly different.
