Is the college entrance examination in different places easy to handle, and is the intermediary reliable?

The college entrance examination in different places, that is, as the saying goes, college entrance examination immigrants, seriously undermined the fairness of the college entrance examination, and the state severely cracked down. I hope I don't trust the intermediary. The intermediary is only for its own benefit, so the intermediary is not reliable. I hope I don't have any illusions, I hope I will abide by the laws and regulations of the country, take the college entrance examination fairly and reasonably, and don't do anything illegal.
