Educational Background and Early Life
S. Nagarajan was born into a family that valued education and public service. He completed his schooling at Chinmaya Vidyalaya in Tirunelveli. Even as a young student, he was fascinated by the impact a District Collector could have on society.
He moved to Rajasthan to pursue a Bachelor of Engineering in Electrical and Electronics at the prestigious BITS Pilani. While his technical education sharpened his analytical skills, he realized midway through his college years that his heart lay in the civil services. This clarity allowed him to begin his mental preparation long before he officially picked up a UPSC book.
How Many Attempts Did S. Nagarajan Take?
Nagarajan’s path to AIR 1 was not a single-shot victory. It took him four attempts to reach the pinnacle:
- First Attempt: He reached the interview stage but failed to find a place in the final list.
- Second Attempt: He secured AIR 137 and was allotted the Indian Railway Traffic Service (IRTS).
- Third Attempt: He attempted the exam while in service but could not improve his rank significantly.
- Fourth Attempt: He took a bold “extraordinary leave” from his training. He dedicated one full year to correcting his mistakes, leading to AIR 1.
The most critical change between his second and fourth attempts was his choice of subjects and his focus on the personality test. He realized that technical subjects like Electrical Engineering were too vast and unpredictable for the Mains.
S. Nagarajan Optional Subject: The Bold Switch
Nagarajan originally chose Electrical Engineering and Physics (two optionals were required then). Despite being an engineer, he found that the UPSC syllabus for these subjects was significantly more theoretical and time-consuming than his college curriculum.
He made the difficult decision to switch to Geography and Sociology. This wasn’t just a random choice. He selected Geography because it was semi-scientific and visual, and Sociology because it was manageable and had high overlap with the Essay paper.
| Attempt | Optional 1 | Optional 2 | Result |
|---|---|---|---|
| 1st & 2nd | Electrical Eng. | Physics | Rank 137 |
| 4th | Geography | Sociology | Rank 1 |
UPSC Preparation Strategy of S. Nagarajan
Nagarajan treated UPSC like a project. He didn’t believe in counting hours but in completing targets. He broke the syllabus into small, digestible modules.
Prelims Strategy
He focused heavily on basic NCERTs and previous year question papers. He believed that the Prelims is less about knowing everything and more about the “art of elimination.” To sharpen this, aspirants today often use tools like MCQ Practice for Prelims on AnswerWriting.com, which allows for topic-wise drilling to ensure no conceptual gaps remain.
Mains Strategy
For the Mains, he followed a “note-making” approach. For every sub-topic in the syllabus, he prepared a 200-word template. This meant that on the day of the exam, he wasn’t “thinking” of what to write; he was simply “retrieving” his pre-prepared templates.

Mains Answer Writing Approach
Nagarajan’s answer writing was structured and visual. In Geography, he ensured that every answer had a map or a diagram. He argued that a diagram conveys in ten seconds what a paragraph takes two minutes to explain.
For Sociology, his answers were balanced, presenting multiple sociological perspectives (Marxist, Functionalist, etc.) for every issue. He emphasized that handwritten practice is the only way to build muscle memory.
In the modern context, getting this practice evaluated is crucial. Platforms like AnswerWriting.com offer an Optional Evaluator that benchmarks your answers against subject-specific standards, much like the peer-review system Nagarajan used during his stay in Delhi’s Rajinder Nagar.
Interview (Personality Test) Experience
In his earlier attempts, Nagarajan’s interview scores were average (around 150-160). For his fourth attempt, he worked on his communication and body language. He realized the board wasn’t testing his knowledge (which was already proven in the Mains) but his “administrative temperament.”
He remained calm when he didn’t know an answer, politely stating that he would look it up. This honesty, combined with his depth of knowledge on his home state (Tamil Nadu) and his engineering background, helped him secure a massive 210 marks.
