The objective questions in the examination mainly include patent law, implementation regulations and examination guide, as well as some related laws. The first three take the lead and need to be understood and brushed.
The subjective part is practice, which generally refers to writing an application, replying to OA, invalid application, invalid reply and so on. This is mainly to listen to the teacher's class more. If you understand them, you should write them yourself. Many times I thought I understood it, but I forgot it when I wrote it.
There is not enough time. Remember to mock the exam yourself (4 hours) and write every word on the computer. In terms of study, I suggest you just listen to 1 teacher's class and listen to it several times. Don't listen to two teachers, each teacher has a different style, and you will be confused if you listen too much.
