Additional information

Do all colleges read the entire additional information? It is stated that we can describe our life circumstances, and I have i a form of an essay. My actual common app essay has also a very important topic, but I want them to read the one in additional information as well. I have less than 600 words there, but am still worried. Thank you in advance.

They’ll read it. But it isn’t really supposed to be another essay.

Thank you for your answer. Do you think it will disadvantage me? It is the way I understood the question, most of it is about the circumstances, perhaps two sentences are general making it an essay.
