The first is the three-year simulation of the five-year college entrance examination, which is really good. Some of our problems are similar to the above.

Another suggestion is to buy the mid-term exam questions in your province and region. After all, there are only so many math problems. As long as you do more and change more, you will get it.

If you haven't read some materials, I don't know if it's worth buying. According to my experience, there is another trick.

(Maybe the landlord knows, but just in case, write it down ~)

Open the first or last page of the information manual. If there are more than three editions or prints, the quality should be better.

The last method is to ask the teacher what books are better. Teachers usually buy some reference books. I don't know about other teachers, but our math teacher has at least four different reference books.

In short, as long as you have the heart and are willing to work hard, I believe you will have a good result ~ Come on, landlord and Minsan ~
