The prompt sounds simple enough. It is the surroundings in which you live, after all, in case there's one subject you know something about. But don't be fooled by how accessible the question appears to be. Admission to the University of California system is remarkable competitive, especially for some of the more elite campuses, and you should think carefully about the subtleties of the prompt.  Consider the purpose of the essay before answering the question. The admissions officers want to get to know you. The essays are the one place where you can truly present your passions and personality. GPAs, test scores and other quantitative data do not really tell the university who you are; they show that you are a capable student instead. But what really makes you you? Each of the UC campuses receives far more applications than they can accept. Use the essay to show how you differ from all the other capable applicants. The personal statement is, obviously, personal. It tells the admissions officers what you value, what gets you out of bed in the morning, what drives you to excel. Make sure your response to prompt #1 is specific and detailed, not broad and generic.

The prompt gives "your family, community and school" as examples of possible "worlds," but they are just three examples. Where is it that you truly live? What really makes up your "world"? Is it your team? The local animal shelter? Your grandmother's kitchen table? Your church? The pages of a book? Someplace where your imagination likes to wander? Focus on that word "how." How has your world shaped you? The prompt is asking you to be analytical and introspective. It is asking you to connect your environment to your identity. It is asking you to project forward and imagine your future. The best responses to prompt #1 highlight your analytical abilities. It's easy to focus on that teacher or parent who pushed you to excel in case you write about your family or school. This isn't necessarily a bad approach to the essay, but make sure you provide enough specific details to paint a true portrait of yourself. Thousands of students could write an essay about how their supportive parents helped them succeed. Make sure your essay is about you and isn't something that thousands of other students could have written.  Adversity sometimes shapes us more than positive experiences. Feel free to write about them in case your world has been filled with challenges. You never want to sound like you are whining or complaining, but a good essay can explore how negative environmental forces have defined who you are. You have just 1,000 words with which to answer prompts #1 and #2. That's not much space. Also you have to cut anything in your essay that isn't defining your "world" and explaining "how" that world has defined you. Prompt 2 is also very important for all the students so they have to learn more about it.
