Tsinghua edition textbook
Three months before the exam, I watched the Tsinghua version of the national computer technology and software professional qualification (level) exam: software designer course (I don't think I need to read other textbooks, this one is enough).
It has advantages for fresh graduates.
Personally, I think this certificate is worth a test. Although it should be of little use to programmers with work experience or training experience, it can make resumes colorful for newly graduated students, at least having some advantages over others.
The exam is not difficult.
The test scores in the morning and afternoon are above 50 points. It should be said that it is not very difficult. Our class got 5 and failed 1.
