You don't need to talk about your achievements in this essay. When you are asked "What can you offer NYU?" the main consideration for your response must be academic and social setting of the university. Take your cue for the response from the fact that the prompt describes NYU as
global, urban, inspired, smart, connected, and bold.
Your response should reflect a similar answer. Highlighting the best character traits you have as a person and a student. Your achievements can be saved for a different and more relevant essay prompt. Right now, concentrate your answer on portraying the best traits you have that relate to the way you can enhance the NYU student community. By the way, about what NYC has to offer you, try to be more specific. Right now, you are talking in general terms instead of showing the kind of interest that a potential NYU student may have in the academic and social community of the school. Talk about some groups you look forward to joining and some projects that you feel you could spearhead at the university in order to enhance the academic and social experience of the students over the next four years.
