During the competition, the team members can use various books, computers and software to browse online.
So in my opinion, as long as you have learned a certain amount of advanced mathematics and are not too stupid, you can take part. I suggest you attend. Participation is the main thing!
I hope I can give points ~ ~
There is also that the topics are not very professional, and most of them can be understood by consciousness ~ only a few topics have unfamiliar backgrounds, but you can check the information and it will be clear at a glance. In short, it will not be particularly biased, as long as you have a certain foundation in advanced mathematics!
