Overall, the real problem of 20 16 is more difficult than that of 20 15, and the difficulty coefficient is basically the same as that of 20 14. The number two is particularly difficult; On the count of three, the difficulty coefficient is moderate.

The first difficulty coefficient of mathematics is relatively high, slightly lower than 20 14, and about 36 points are rare sub-topics or off-topics.

The second difficulty coefficient of mathematics is particularly high, which is seriously higher than 20 14, and about 40 points are rare sub-topics or off-topic questions.

The coefficient of three difficulties in mathematics is moderate and quite satisfactory, which is much lower than 20 14. About 2 1 is a difficult problem, or a partial problem.
