I come from a family of modest means, and my parents always encouraged me to pursue my dreams. I was fascinated by mathematics from a young age and excelled in it throughout my school days. I knew that I wanted to pursue a career in civil services, and mathematics was my optional subject of choice.
I started preparing for the UPSC CSE exam about 2 years before the actual exam date. I created a detailed study plan that included a mix of theory and practice. I focused on completing my syllabus for the general studies paper first and then moved on to the mathematics optional paper. I used a combination of NCERT textbooks, standard reference books, and online resources to prepare for the exam.
One of the biggest challenges I faced during my preparation was balancing my studies with my part-time job. I had to work for about 6 months to support my family, and it was tough to manage my time effectively. However, I was determined to crack the exam, and I made sure to allocate dedicated time for studying every day.
My interview experience was quite smooth. The panel asked me a mix of general awareness and mathematics-related questions. I was well-prepared for the interview, and I could answer most of the questions confidently.
I attribute my success to my hard work, dedication, and the right strategy. I was consistent in my preparation, and I never gave up, even when things got tough. I also believe that having a strong support system, including family and friends, played a crucial role in my success. If you're preparing for the UPSC CSE exam, my advice would be to stay focused, work hard, and never lose sight of your goal.
