First of all, I admire that you can set yourself the goal of the college entrance examination now, and sincerely hope that you can achieve it within three years!

I graduated from Dalian at the age of 24, and got about 120 in the senior high school entrance examination, but got 142 in the senior high school entrance examination, which should be relatively high in that year. Therefore, as long as you are willing to work hard and pay twice as much effort as others, it is possible to get an ideal result in the college entrance examination.

Besides, I'm worried about your present situation. I hope you don't give up the simple questions, the ones you can do, and the ones you have done in a month. In my experience, if you can do everything right, you can basically get 120. All the difficult problems are composed of simple questions. You can only ask the first question, which shows that you still have some strength, but your learning direction needs to be adjusted. Never think that doing simple questions is a waste of time. In addition, it is also helpful to look at the previous wrong questions before the exam, which can at least improve 10 points.

I hope you can get good grades!
