Difficult, for people who lack practical work experience, it is really not easy, because they need the background of specific operation content and the experience of applying specific knowledge points in the field of project management in practical work.

No, it is not difficult for people who are familiar with various knowledge points in the field of project management and have practical work experience. You just need to remember the knowledge points in the top ten areas of PMBOK and combine them with practical work experience.

As for how to write, I think we can combine (experienced)/simulate (inexperienced) the actual operation process of a project and describe all the knowledge points we need to write in the field of knowledge with practical experience. As long as it doesn't deviate too much from the subject, it's basically the same, and passing the exam should be no problem. But if you want to get high marks, you still need to work hard.
