Generally speaking, the beginning is the hardest, and then the end. The mid-term whole should be the simplest, but it does not rule out the difficulty of single subject. Usually, the average score of exams is around 7 or 80, which is not particularly difficult, but there will be more difficult exams every once in a while.

I am a student of Lida Grade Three, and I don't care about most of the usual exams in Grade Three.

PS: The first mode is the most difficult, the second mode is the simplest, and the difficulty of the senior high school entrance examination is moderate.
