Look at your level. If you graduate from a normal school and have a solid professional foundation, you can review at home.

If your foundation is not very good, you can sign up for class.

In the first case, I suggest that you start downloading the app brush questions a few months in advance, or you can buy some cheap online courses to learn about the test sites. In addition, buy a set of real test papers and take a mock exam once a week. Let yourself improve the speed of doing the questions, and you can also find your own weak points. Strengthen early.

I hope my answer can help you ~
