1, local special edition. Generally, the cover will be marked with the words "Sichuan Special Edition" and "Chengdu Special Edition". This kind of examination is specially compiled according to the examination situation of each province or region. Is the most suitable. However, if a province's senior high school entrance examination does not use a unified test paper, or if the book's local sales are very small, there will be no special edition.

2. News version. Generally, the cover will be marked with the words "People's Education Edition" and "People's Edition". This kind is distinguished according to teaching materials and publishing houses. You can look at the publishing house of the textbook you use, and then find the corresponding teaching AIDS.

3. National edition. Generally, the words "ordinary edition" and "curriculum standard edition" will not be marked on the cover, which is not suitable for the senior high school entrance examination, because there are not many provincial unified examinations, and most of them are based on regions, and there is no national unified examination. But good books can also be used.

There are two more convenient ways.
