Why is the high school mathematics competition in Hunan Province divided into volume A and volume B? If you get the second place in this A volume, can you get the qualification of independent enrollment? Students in Grade Three and other grades who are interested in participating in the national league must use Volume A, and students in Grade One and Grade Two can use Volume B ... I wonder if the league is like this? The proposition of volume A is not beyond the range of 20 12 college entrance examination mathematics proposition; The proposition in volume B does not exceed the scope of the 20 12 high school mathematics proficiency test.
