Jiangsu Province is an autonomous province. Of course, I bought your Jiangsu edition. As for the AB version, there was the A version in the first half of this year, but there were no college entrance examination questions this year. Version B in the second half of the year has this year's college entrance examination questions, and the classification is very good. If the teacher asks you to buy which version and you do the questions yourself, I suggest you buy version B, do more college entrance examination questions and learn more about the trend of college entrance examination questions. Its answer is very detailed, and you will understand if you do more. If you are satisfied with the answer, please accept it. Thank you!
