I took the fifth exam last year and registered on the official website of Qiu Chengtong University Students' Mathematics Competition. I just need to register in official website about one month before the exam. If the registration is successful, the teacher of the relevant division will tell you the time and place of the exam, but it's not time for the exam, so I can't register yet.

Autumn competition is really difficult. If you want to get good grades, you must prepare hard. I hope my answer can help you.
