The aim of such an essay is obvious: you need it to convince admissions officers to accept you into college. As a rule, there is a word limit specified in the instruction for applicants. Don’t confuse an autobiographical essay with your CV or resume! They have totally different structure and formatting. In addition, the essay is aimed at portraying you as a personality, not as a professional.
Yes, you have to be precisely honest and quite revealing and candid to write a successful autobiography. And obviously, you need to describe some hardships of your life to show how you coped with that or how it influenced you. However, we strongly advise you to describe the thing that you feel rather calm about when writing. For example, you are writing about other students picking and making fun of you at high school. If you still feel like wanting to kill them all, it would be better to avoid this topic or mention it slightly. Why so? Because your feelings will leak into the writing and make your reader feel subconsciously uncomfortable.
The main body includes the biggest amount of information. It is 80-90% of the whole text. There are no strict requirements, but you should not forget to use a logical sequence and correct wording. You can use the classic five-paragraph structure for your autobiographical essay if your ideas fit it. Anyway, you have to divide your writing into separated paragraphs to increase the readability of your essay. You should also create a logical connection between paragraphs. In this manner, readers will easily follow your thoughts.
Writing an autobiography for a high school or a college English class can help you gain a deeper sense of personal identity. An autobiography allows you to tell your story in a way that reveals truths about your values, goals and dreams. Though there's no exact science to writing an autobiography, you should include information about your background, major events that shaped who you are and any core themes in your life. Include specific examples to help readers understand your life history.
