I'm also going to take the exam in Chengdu No.7 Middle School, but I took it this year. You are much better than me. You still have one year to prepare. My grades were not bad, and I planned to enroll in the pre-test special class in the first-tier schools at that time. I hope I have a chance to be admitted. The following is an answer that is close to your question that I forwarded. Do you think it's appropriate? I collected this information when I was thinking.

1. Mathematics and English are the most difficult topics in Chengdu No.7 Middle School, and mathematics is basically the difficulty of the national Olympic Games. You should make more efforts in this respect. English vocabulary is large, especially reading is difficult and there are many questions. Expanding vocabulary is the key. You can make some newspapers and other materials, in which key phrases and words, whether you know them or not, will be remembered and consolidated.

2. Generally, the first prize of the national competition will be awarded extra points, and you can participate in the corresponding competition on the premise of strengthening the foundation. There are no extra points in other competitions, but they will be admitted on the basis of merit. If you have studied olympiad, you will have a greater advantage.

Chengdu is the most in 3.4, 7 and 9. 4 or 9 times, but it can be considered, because it is one of the best middle schools in the province.

I wonder what the English teaching level in Yibin is. I come from Nanchong, but students from other cities have always been good at math and physics, so English is more difficult. (I took the exam in our county, and my English score was 150, with a maximum score of over 60. ) I suggest reading new concept textbooks.

I tried my best for your reference.
