If you want to concentrate on the exam, you can actually choose to watch video courses. The special exam also has a lot of audio review materials, then take notes and brush the real questions at the same time, just in these four directions.
The most important thing is to brush the questions. There are many laws and regulations. You can listen to the audio to find the key points, and you can listen to the "Xi Shuo" on the Himalayas to explain the examination guide and patent law. As for the review methods, I suggest looking at some review ideas. If there are some video courses, check Baidu, or go to the online school of intellectual property class, listen to the video and audio explanations, then take notes and brush the real questions with the special learning and problem-solving system inside.
