In this blog post, I’ll summarize the academic experiences and school activities I accumulated during high school, examples of my consideration and cooperation, and my career preparation process.

Academic Experiences and Reflections

During high school, I particularly enjoyed math. I always sat in the front row during class and took meticulous notes; I even enjoyed solving short pop quizzes as if they were a game. As the math class representative, I had many opportunities to communicate closely with my teacher, and through that process, my interest in mathematics as a whole deepened.
Among these topics, the area that interested me the most was statistics. I approached not only the statistics unit I learned in my freshman year but also the statistics content covered in my sophomore year with consistent enthusiasm. In particular, when taking classes using the textbook ‘Fundamentals of Calculus and Statistics’, I went beyond simply previewing and reviewing to ace exams; instead, I repeatedly previewed and reviewed out of intellectual curiosity.
I transcribed the textbook’s theories into my own notebook and reorganized the structure and flow of each unit to create “my own textbook.” I also personally restructured the core theories, formulas, example problems, and advanced problems for each unit and shared them with my friends. This notebook, which I named “My Own Calculus and Statistics Fundamentals,” was not just a collection of notes but my own study guide that restructured the course material.
Although this method took more time, it deepened my understanding of the theories and formulas. In particular, creating new problems required a complete understanding of existing questions and an ability to reverse-engineer the calculation process, which served as training in interpreting the intent behind exam questions. Through the process of designing problems, I developed the ability to view questions from various perspectives.
Thanks to this process of organizing material and creating my own problems, I frequently scored perfect marks on exams and became much faster at solving problems. My friends often asked to study using my notebook, and seeing them do so gave me a sense of accomplishment as well as the joy of teaching.

Major Campus Activities and Reflections

Due to my meticulous nature and tendency to analyze situations through numbers, I naturally took on tasks such as budget management. I primarily served in administrative roles on campus, and during my sophomore year, as a member of the Student Council’s Administrative Department, I gained hands-on experience by directly handling the details of the school budget allocation process.
My primary duties in the General Affairs Department involved receiving budget requests from clubs and other student council departments, reviewing the appropriateness of the requests, and gathering related suggestions. I was also responsible for managing fines imposed for violations of school regulations and other sources of revenue. I carried out these tasks in collaboration with other members of the General Affairs Department, which gave me a sense of fulfillment in directly contributing to students’ campus life.
When reviewing budget requests, I would allocate funds based on the number of members and activity plans for new clubs, or—in the case of existing clubs—approve or defer requests by considering the transparency of past budget execution and the results of their activities. Through this process, I learned that budget allocation is not merely a matter of simple calculations but requires fairness and accountability.
On one occasion, an existing club misused its allocated budget for personal purposes and engaged in underage drinking. As a result, the club received severe disciplinary action, and measures were taken to cut its budget and dissolve the club. At the time, the members of the General Affairs Department were also reprimanded, and I, too, could not escape a sense of responsibility.
Going through this incident made me keenly aware of the critical importance of budget management and auditing. Since then, I have adopted a more thorough approach to budget planning and execution management, and this experience confirmed my aptitude for fields such as accounting and auditing, including a career as a certified public accountant.

Examples of Consideration, Sharing, and Collaboration, and My Reflections

In my first year of high school, I joined the marketing club, where I learned the values of collaboration and sharing by planning and executing various economic activities together with my peers. Through the process of planning activities and sharing profits with my club members, I felt a strong sense of belonging and accomplishment.
The most memorable activity was running a flea market during the fall festival. Since our club room was too small, we planned a profitable festival program to secure a larger space, and we prepared meticulously with my fellow members to achieve that goal. To identify items that would sell well and secure sufficient quantities, I visited wholesalers in person and purchased unused workbooks and clean books at low prices from acquaintances and upperclassmen.
On the day of the festival, we laid out stationery and books on large tables and sold them for two to three times the purchase price, generating more revenue than expected. Celebrity-themed stationery, in particular, was a huge hit, and when my idea for an impromptu auction was adopted, sales revenue increased even further. The sense of fulfillment was even greater because we achieved this result by working together with my club members despite the hot weather.
We submitted the proceeds to the Student Council’s Finance Department to request funding for a larger club room, and our request was approved, leading to an improvement in our club’s facilities. Through this experience, I personally felt how the power of collaboration and the process of sharing profits toward a common goal strengthen a sense of belonging and trust among members.

Efforts and Preparation Related to Motivation for Application and Career Plans

My upbringing had a significant influence on my career decision. My father worked for many years at the National Statistical Office, handling tasks related to economic indicators such as price trends and income statistics, and he always advised me that a thorough understanding of statistics is essential for research. Seeing him like that further fueled my interest in statistics and numbers.
At first, I considered majoring in statistics like my father to become a statistics expert, but after weighing his advice against my own inclinations, I decided to pursue a degree in economics. I was particularly interested in budget management and auditing, and these aptitudes and interests naturally led me to the career path of a Certified Public Accountant (CPA).
My parents always respected my opinions and listened attentively to even my smallest concerns, and I have always been grateful for that family environment. With my parents’ encouragement and advice, I solidified my career path during my senior year of high school and concluded that becoming a CPA was the right fit for me.
Since entering college, I have dedicated myself to my studies and earned a scholarship. I have been steadily preparing for the CPA exam subjects—including Accounting, Principles of Economics, and English—since my freshman year, with the goal of starting my professional career earlier than my peers. Ultimately, I aim to become a CPA to repay my parents’ support and, drawing on the statistical thinking my father emphasized and my campus experiences, become a highly skilled accounting professional.
