Postpone the test before the exam, that is, by studying the previous test questions and ideas, and relying on rich experience to guess the topic scientifically. To put it bluntly, it is to hire several industry experts with high salaries, ponder over all the papers over the years, and then study the direction of this year's questions and make a bet. There is basically no original title, but there are some similar topics. But it's hard to say, depending on luck, the question bank is different every time, and the examination questions are different. Lucky, most of the questions are familiar, unlucky, just a few questions. Of course, we can't rely entirely on this. After all, learning is not "gambling". It is also one of the important purposes to promote learning by examination and learning by examination. Remind the landlord that betting has luck, and not every year you can bet on some real questions. In the final analysis, we still have to work hard and review it several times. If you are still not sure, think again. After all, there is more security and more peace of mind.
