As Pash mentioned, reviewing the requirements on the tryout announcement is important since many individuals overlook some of the elements that we look for. Swimming, like Cheer and Track, is mostly detailRP, which is why it is critical not to cut corners.
Have your actions ready before the tryout, it shows devotion and saves a lot of time!! (As some others would make their actions right on the spot and the tryouts end up extending. . .)
Make sure you know anything about the sport, because it will show and increase your chances.
If there is a specified swim speed or lung capacity, work them out ahead of time.
As for being on the team, continue to show interest and participate in practices/events, tryouts, and so on! Even if the difficult phase (trying out) is over, you should continue to exhibit interest in the team. As previously stated, the sport will be completely detailrp, yet both swim teams often find other things to do during practices outside detailrp.
