How to rank the difficulty of one model, two models and college entrance examination in Shanghai? Which is more difficult, the same model or the college entrance examination? Ask for a detailed answer! It used to be between the national examination and the college entrance examination, and the second mode was more difficult than the college entrance examination. This is basically the case now, but in the past two years, some subjects, such as mathematics, have been far more difficult than the second model. Secondly, the second model is always imitating the college entrance examination model of the previous year. The score of the second model can't explain the problem, but the ranking of the scores of the second model in the district can still explain the problem.
