China's patent agent qualification examination registration requirements clearly stipulate:
Article 15
(4) Having been engaged in scientific and technical work or legal work for more than two years.
Therefore, students are not allowed to apply for the exam.
I suggest you start preparing patent-related laws now. If you have nothing to do, you'd better take the judicial examination yourself, because you have to take other related laws (including civil law, criminal law, contract law, administrative law, intellectual property law, etc ...), and then start preparing patent agency practice one year before the exam, that's all.
I wish you success.
