I have more say, because I come from CCCC. Look at the passing rate in the vocational qualification exam, and everything else is bullshit. No matter how good it is, it's all over without a pass rate. Every year, the company spends a lot of money to invite several teachers from Zhang Xian, Zhou Chao to teach road engineering and bridge and tunnel engineering face to face, and the passing rate should be between 30% and 50%. It should be said that it is about twice as high as the passing rate of social evaluation, and it is also worth the training fee, so it is also a fixed cooperation every year. Our company is engaged in online courses and offline lectures. Before face-to-face teaching, their online school will build a group to urge them to go through the online courses, and then have another face-to-face teaching before the exam to sprint on the spot. Anyway, the course schedule is full, and it is difficult to keep up with this rhythm. Those who fail the exam are basically half-baked, and don't learn that.
