Personally, I think the middle point in the book is more comprehensive for people with good grades or poor foundation.

And winning the championship easily is for students who need to sprint with medium grades.

It depends on what kind of person you belong to

As for the view upstairs, I don't agree.

My three national mathematics awards are all LZ questions that I have practiced, and it is not necessarily bad to repeat them.

Math achievement comes from practice. I won't lie to your teacher to reduce the burden and do well in the exam. That's a lie. This is either a foreign education system or an examination.

So it's better to practice more. Of course, if you don't have time, consider some of my opinions yourself.
