National Volume I (Hebei, Henan, Shanxi, Guangxi) National Volume II (Heilongjiang, Jilin, Yunnan, Guizhou, Xinjiang, Qinghai, Gansu, Inner Mongolia, Tibet) Sichuan Volume Chongqing Volume Shaanxi Volume Hunan Volume Beijing Volume Shandong Volume Hubei Volume Anhui Volume Jiangxi Volume Fujian Volume Tianjin Volume Shanghai Volume (3+ Comprehensive+1) Liaoning Volume Jiangsu Volume Guangdong Volume (3+) I feel that the national 1 is more difficult, and the national 2 is slightly inferior. The topic of Shanghai and Jiangsu is relatively novel, but it is not difficult to do it with a solid basic knowledge. In fact, the difficulty of the topic is related to the topic given every year, which may be difficult to say. Chemistry in Shandong is very difficult this year. In short, in a word. It is not difficult to meet, but it is not difficult to meet!

Satisfied, please adopt.
