First of all, this student is definitely not blind. According to the probability, he only has 1/4. Luck may be greater than this value, but it is impossible to be lucky every time.

Personally, I think he should have strength. For uncertain questions, the elimination method is adopted, and the answers of the upper and lower questions are combined to make a "blind test". For example, the answer to the previous questions is ADBB (? ) d, if you rely on "Meng", generally choose A or C, and it is best to exclude A, you will be more sure, hehe.

To sum up here, if you encounter a problem that you can't do, of course you can't leave it empty. At this time, you must rely on "Meng"

First, make sure that the questions before and after are correct (otherwise it will affect the accuracy of doing the questions), and then go back to the questions that you can't do and eliminate as many as possible. Every time you exclude one, your chances will increase by a few percent.

Secondly, combining the answers before and after, the ABCD options of general exam answers are generally balanced, and the options with less frequency are selected after exclusion.

I hope it helps you! Good luck!
