But I want to bless you, don't believe this too much. It depends on your own ability. I have studied this before. But you get an average score on this basis, and you always doubt that you are wrong. Then you changed. But most of the changes are wrong. Although you also have five options, there are many mistakes.
And sometimes the options are not five, but four, six, five, five or three, seven, five, five (less) or four, six, four, six and so on.
This method can only check. Estimate your own right and wrong. Instead of changing your answer according to him.
That's all.
Please tell me if you have any good application methods. The above is my experience.
