I just have a “passion” comment. Most 13/14 year olds don’t have a passion. No AO asked us what either of my kids’ passion was. They ask about subjects they like, ec’s they like. What they enjoy doing out of school. You need to be interesting and have things to talk about but most BSs assume they are the place you might find your passion, or at least a direction.
You need an application that shows who you are in a well organized manner. But having a passion at 13 is silly. Interests yes!
