The national volume (A) is more difficult than the second volume, but simpler than the local proposition, because we have to take care of the actual educational situation in most provinces. It actually depends on your own level. My senior year is a graduate of 20 14, and now I am studying in the School of Computer Science and Technology of Jilin University. I had the same problem before the college entrance examination, but I adjusted my mentality to make myself better and review according to my own plan. If the topic is difficult, everyone is difficult, and the simple one is simple, which makes no difference. Success is doing what you can, without losing points. I wish the college entrance examination success. Welcome to Jilin University, the famous 985 engineering school.
