Generally, the longest preparation time for preparing for the computer level 2 exam is only three months. There are also many people who sprint for a short time and then get a license.

Mainly because of the second-level examination mode: there is a basic question bank, which will be added every time.

If you have enough time, you can buy a textbook+computer software (real test simulation software)

In this way, start with the problem and look at the textbook to solve the problem.

If there is not enough time, directly buy computer software (real question simulation software) combined with real question analysis and brush real questions.

Textbook: recommended by colleges and universities, explaining test sites based on real questions.

Software: I recommend Hu Ben's computer software. The grading system is consistent with the real exam (although there are some minor flaws, it at least improves the preparation effect.
