Disadvantages: 1, the judges' scores are generally not high, because once they are high, it is difficult to judge whether they have a better score unless they perform well.
2, the first experience, no previous performance for reference.
3, the beginning should be the most nervous.
Generally speaking, the advantages outweigh the disadvantages. After all, it is a competition, so we will pay more attention to scores and rankings. However, we should also treat the game well and try our best to give full play to it.
I still hope you can get good grades!
