It depends on how many points you can get in the real question now. The number two of 20 15 is very simple. If that piece of paper can score 70 points, it is still promising to sprint for a month.

If you haven't reviewed it much, it's too difficult and almost impossible. I studied for two months, three or four hours a day, and I think I can get 60 or 70 points in the exam. If the foundation is not good, there is really no hope for a month.
