The first time I learned about this thing, I was afraid it was a bit unreliable.

Where did you know that? Are they some examination and training institutions? Mark my words, don't believe it. It's no use. If you want to pass the exam, you must study hard. If you don't work hard at ordinary times, it is impossible to get something for nothing by passing the final paper. Training institutions have seized the luck of some people, even three days before the final exam, there are all kinds of classes and top secret papers, and the fees are very high, and some even cost more than 10 thousand! But the final results are basically fake! What I said before paying the money is very simple. All the agreements have been signed, and the bottom is guaranteed, but the fees will be refunded and the next semester will be free! Fail this semester and study for free next semester. Can you still study? Refund is not a full refund. It is estimated that you will deduct about 20% of the material cost, management fee and so on. Anyway, don't believe it! If you participate in normal and formal institutional training similar to civil servant training, it is ok, mainly to explain the ideas and methods of the topic to you. If you get straight to the point, I advise you to give up the idea at once! To tell the truth, before the state did not strictly supervise the examination, there were missed questions and missed questions, and there were so-called betting questions. At present, the state controls the examination very strictly, which basically eliminates the problem of missing questions. So please believe me, don't buy a bet, read a good book, and you will definitely achieve the result you want. Wish you success!
