I am a senior three student this year. In my freshman year, I took the pilot test to make up for it. In fact, the price is similar to that of other institutions, and it is also recommended by school teachers. But then I heard that the class teacher took the money, and it didn't improve after a year's compensation. I don't evaluate the effect. Learning this kind of thing is a problem for both the school and me, but the teacher is really irresponsible and not as good as I said before.
