I don't know where you come from, and I don't know which province you come from. Now several provinces in China are doing teaching experiments. In Jiangsu, the new curriculum standard version of high school in February, which started in September, is a Jiangsu science and technology version. From Grade One to Grade Two, it is divided into compulsory courses 1, 2, 3, 4, 5. However, Anhui and other places are still using the previous People's Education Edition.
