I’m sorry now you have been on the team for 5 but you’ve been saying “one”. And again, what are the other years of swimming if you have not been on a team. It may be an activity to list but so is coloring, doing sudoku, watching TikTok’s, etc. There is a different level when a 13-14 year old is listing 8-10 years of doing activities, MANY activities, but defining your level of commitment says much more to an AO than just a mention. Even in your listing of horseback riding when you competed for finals, did you make it to finals in a single show? Are you consistently making it to finals, or was this when you were 10 years old? Not sure what a contremaster is, but what 2 orchestras (school, regional, national), was this for a single concert or a whole season, what are your responsibilities, are you conducting? Is there a reason as to why you are in the US and tested for a British music theory exam, and how do you earn a 9 on an exam when the highest is grade 8?
Again, I would look long and hard at your list of activities because AOs will see through contradictions and errors that are like a beacon of light when students exaggerate these lists they concoct for their applications. It won’t bode well for a decision that you desire.
