It's hard to say exactly how many books were published that year. There are three volumes in the national volume 20 16, and 20 17 is unknown. Maybe there are two more. This will be announced a few months before the exam. Of course, in fact, this is not directly related to the college entrance examination.
Second, sub-region: the direction of the test questions mainly depends on where you are. If you are in a relatively developed province and city, then the test questions don't need such high accuracy to master your knowledge points. The direction of the test questions is mainly in-depth, mainly to test the candidates' flexible use of knowledge points.
Third, the degree of education development: the examination questions in underdeveloped areas usually take one or two relatively biased knowledge points, or are usually relatively rare questions, such as this year's national three volumes. Candidates usually train in the direction of the former, which leads to the difficulty of three volumes this year more than one or two volumes.
