A difficulty coefficient of > 0.8 is a simple question (sub-question), a difficulty coefficient of > 0.5 is a relatively simple question (basic question), and a medium difficulty question is between 0.3 and 0.5. Most of the real questions in the postgraduate entrance examination are basic questions and medium questions.

The difficulty coefficient is the data reflecting the difficulty of the test questions, which is different from the difficulty (expressed by P) and is equal to 1-P in numerical value. The greater the difficulty coefficient, the higher the score rate of the topic and the smaller the difficulty. The smaller the difficulty coefficient, the lower the score rate and the greater the difficulty. The difficulty coefficient can be understood as the degree of difficulty.
