n this type of essay, it is better to demonstrate your qualities, rather than just claiming to have them.
Great advice, here... that is why people say: Show, don't tell.
But it is difficult, Amaris, because the prompt asks you to tell about those qualities. So... the trick is to SHOW your qualities by telling some examples of things you have done to PROVE it. Next, tell some examples about your intentions (i.e. what you WILL do as a student at that school). Finally, end by naming the qualities in a way that will stick in the reader's mind.
