How can I put it? 20 12 should be 80% easy and 20% extremely difficult! Candidates will be OK as long as they successfully complete 80%. The super questions are 14, answer 18, ask the third question/question 19, question 2/ question 20 and additional question 23. These questions are left to the candidates of Chongming University. Therefore, the distinction of mathematics should be strengthened this year. The easy questions are easy, and the difficult questions are very difficult. 80% questions make most candidates laugh, but 20% questions make them laugh (even cry). It is not surprising that some candidates think that the difficulty of mathematics is generally not high this year, because 80% of them are easy to use. In fact, it is very difficult to get a high score above 170 in 20 12 mathematics.
