First, you need to be familiar with the exams over the years. You must first figure out what is being tested in order to know yourself and the enemy. Second, after clarifying the examination subjects, you can start preparing for review. During the review process, you must first change your mentality, because many of them are working and may be reviewing while working. This is a test of self-control. It's time, now that you have chosen to take the exam, don't give up halfway. You can browse the exam announcements for the area you are applying for to find out the content of the subjects examined. Because the content of the examination may sometimes be adjusted, you should pay attention at any time. The third thing is to do more real test questions. You must do the real test questions several times over the past years. Check for omissions and fill them in, and discover your own weaknesses so that you can make better progress.
