比如：
The Durham Youth Commission is a teen-led faction of the Durham County government that was created to provide youth input in local politics. To get into the Commission, applicants must submit a thorough description of their extracurricular and academic interests as well as answer questions about what they would like to see accomplished during their time in office. Out of 100 applicants, I was selected to serve on the commission two years in a row along with about 25 other high schoolers attending school in Durham. Along with promoting efforts to combat gun violence during my time serving in the DYC, we also pursued advocacy projects to address mental health challenges and food insecurities. The Commission was regularly updated by various city officials about the nature of their work, including the mayor of Durham. The DYC also attended several conferences hosted by other city youth councils to build leadership and communication skills as well as encourage active community involvement. I volunteered over 60 hours each term. I served on this commission for organizations like Mobile Market, Peace Toys forward Toys, Habitat for Humanity, and Kids Voting. (187 Words)

不过，所写的内容一定要合情合理，而非狡辩，尽量简洁，以下是一个可供参考的示例：
I dropped water polo and cross country after sophomore year due to chronic back problems. My back healed by Junior year and I returned to water polo as an assistant coach but chose not to return to the cross country so I could focus on academics and get a job to help pay bills at home.
如果家庭成员残疾或无法工作，并且这对你的生活或学业产生了影响，你可以考虑简短地解释一下相关信息，以下是来自三名学生的例子：
I would like the admission committee to know that my younger brother has spina bifida and my family and I devote a considerable amount of our free time to his care and trips to the doctor. It also means that my mother has not been able to work outside of our home since he was born.
In 2018 my father suffered a series of strokes which left him partially paralyzed and with severe cognitive impairment. He was obviously unable to continue his career as a professor at the local university. With the help of many therapists and medical professionals my father has slowly gained back some of his faculties, but it is rare that he is left at home alone. My mother and my brother and I are typically by his side making sure he has what he needs and that he is safe. For the first half of last year while my father’s condition was critical my mother was unable to work at all.
My mother is a beautiful, warm, and passionate person. Sadly, she also suffers from schizophrenia which she allows to be treated only periodically with medication. She is rarely able to hold a job for more than a few months at a time, and our family depends on my father's job driving heavy equipment for the city for income as well as insurance. Dad isn’t able to take time off on those days or long periods of time when mom needs extra attention. My sister and I have taken over household chores and bill paying to fill in some of the gaps.
以下是一个描写IB Extended Essay的例子：
For my IB extended essay requirement, I wrote a 4,000-word thesis arguing that French art film director Gaspar Noébreaks the conventions of classical narrative structure as defined by story theorist, Robert McKee. My close reading of Noé's film Irreversible (2002)seeks to prove that Noé defies McKee's principles of the inciting incident, law of diminishing returns, and balance of high and low pace scenes by Noé'smanipulation of the Russian Formalist elements of fabula and syuzhet.
同样，如果在高中阶段你完成过其他的论文，同样可以用类似的方式介绍，如果论文Abstract比较短的话，也是可以直接复制到Additional Information中的！
任何其他你认为重要的内容
你还可以在Additional Information中附上你个人作品的链接，艺术生可以附上作品集链接。
或者，你可以说：
“I’m one of the first students to apply to U.S. universities from my school OR my school doesn't have experience with U.S.school applications.”
“We don’t have a college counselor, so two of my teachers volunteered to complete the counselor recommendation.”
“My English teacher and I worked together to create our School Profile (not only for me but also for my younger classmates)”
