Is the difficulty coefficient of the gold test paper in the second volume of seventh grade mathematics big?
The difficulty coefficient of the gold test paper in the second volume of seventh grade mathematics is not great.

The gold test paper is not too difficult, only medium, suitable for middle-aged students to train once. There must be some problems, but the overall difficulty is normal.

The difficulty coefficient is the data reflecting the difficulty of the test questions. Different from the difficulty (expressed by P), the greater the difficulty coefficient, the higher the scoring rate of the questions and the smaller the difficulty. Numerically equal to1-p. The difficulty coefficient can be understood as "easy".
