Pedagogy is very sad. Since 20 years ago, the difficulty has suddenly increased. I have seen too many people who have passed the exam for more than 320 years and died in front of the national line. After all, education is a popular major, and the heat will not drop in the future, but will only get higher and higher, so there is basically no possibility of dropping points, and it is very good to keep it from rising; As for why it is difficult to say 340, because there are many specialized courses and the pressure of reciting is great. If it is a unified examination, it will be more detailed and flexible, and the difficulty will be improved. If you can get 230 points, it is already very powerful, but the preparation is ok, and you will wander between 200 and 220. If you match public courses according to this interval, you will basically know the difficulty. It's easier said than done to get 60, but getting 70 is another matter.
