In short, the gold edition is a good review material. If the school orders, just follow the teacher's rhythm.
As for five three.
There are many questions in it, all of which are college entrance examination questions, and they are also very good. You can buy one and do some questions selectively according to your own needs. For example, if you are not good at solid geometry in mathematics, you can do that problem directly. In addition, the above explanation is also very good. I just feel a little jumbled, so it's not easy to find some.
In short, if you make a good study plan for the gold edition, you can buy 5/3 books to increase the number of questions. There are not many questions to do, but understanding is very important.
I wish you good luck in the third year of high school and achieve ideal results in one year.
