In the competitive landscape of UPSC coaching in Kolkata, many institutes claim success, but few can demonstrate a multi-year commitment to a student’s growth. The journey of Rajdeep Ghosh is a definitive case study in how consistent mentorship, rather than short-term test series, creates a topper. From his enrollment in 2021 to securing AIR-789 in UPSC CSE 2024 and qualifying for the 2025 Interview, Rajdeep’s story is a 4-year masterclass in grit and expert strategy.
Today, we delve into the inspiring journey of Rajdeep Ghosh, a name that has become a testament to the power of consistency. From his classroom days at APTI PLUS Kolkata to securing All India Rank 789 in UPSC CSE 2024 and appearing for the 2025 Interview, Rajdeep’s path offers a blueprint for every serious aspirant.
The Foundation: Choosing the Right Starting Line (2021)
Rajdeep Ghosh, a graduate of the prestigious Ramakrishna Mission Narendrapur, began his UPSC quest in 2021. At a time when many aspirants felt the “Delhi pull”—the belief that one must migrate to Rajinder Nagar or Mukherjee Nagar to succeed—Rajdeep chose a different path. He placed his trust in the strength of local, personalized mentorship at APTI PLUS Kolkata.
Enrolling in our 1-year Prelims-cum-Mains classroom program, Rajdeep didn’t just attend lectures; he built a base. This initial phase was about more than just syllabus completion; it was about developing the “UPSC mindset”—learning how to analyze, correlate, and think like a future bureaucrat.
The Strategic Pivot: Turning Setback into Strength (2023-2024)
Success is rarely linear. After a rigorous first attempt, Rajdeep qualified for the 2023 Prelims but unfortunately could not clear the Mains. For many, this is where the dream falters. For Rajdeep, it was where the strategy evolved.
Returning to his mentors at APTI PLUS, Rajdeep joined the Abhyuday 2024 Mains Guidance program. Together, we identified a critical area for improvement: his optional subject. In a bold strategic move, Rajdeep decided to switch from Chemistry to Sociology.
This wasn’t an easy decision, but it was a calculated one. Under the expert guidance of Shweta Madam and our Sociology faculty, he didn’t just learn a new subject; he mastered it. He participated relentlessly in daily answer writing and our comprehensive Mains test series. This phase was the “polishing of the diamond,” where raw knowledge was transformed into high-scoring answers.
The “No-Delhi” Triumph: AIR-789 (2024)
The hard work culminated in the UPSC CSE 2024 results. Rajdeep Ghosh secured AIR-789, proving a vital point to the entire aspirant community: You do not need to rely on Delhi to crack the UPSC. By staying in Kolkata and utilizing the online and offline mock interview panels provided by APTI PLUS, Rajdeep maintained his focus without the distractions or costs associated with moving cities. His success was “Homegrown,” built on the trust he established with his mentors back in 2021. He didn’t hop between multiple institutes for short-term gains; he anchored his journey in one place that was fully committed to his success.
The Pursuit of Excellence: The 2025 Interview
A true achiever’s hunger isn’t satisfied by one rank. Driven to improve his service and contribute further to the nation, Rajdeep appeared for the 2025 exam once again. True to his roots, he returned to APTI PLUS for his Mains test series and Sociology preparation.
Today, as he appears for his 2025 Personality Test (Interview), Rajdeep remains a part of the APTI PLUS family. We have arranged personalized one-on-one sessions and panel mocks across Kolkata and Delhi to ensure he is ready for the final hurdle.
Key Takeaways from Rajdeep’s Story
Rajdeep’s 4-year journey offers three critical lessons for every UPSC aspirant:
- Consistency is King: Success isn’t about what you do in the last month; it’s about the foundation you build over years.
- Strategic Adaptability: Don’t be afraid to change your strategy (like an optional subject) if the data suggests a better path.
- One Constant Mentor: In a landscape of “scattered guidance” and superficial claims, having one mentor who knows your journey from Day 1 is an invaluable advantage.
