Why doesn't Sibo have the problem of 202 1?

The National Bureau of Knowledge does not disclose the exam questions. All the questions in Sibo app examination database come from the real questions of the patent agent qualification examination from 2006 to 20 19. Since 2020, the National Information Bureau will no longer disclose the real exam questions. Over the years, the real questions stopped at 20 19, and there was no question of 202 1.
