I am deeply thankful to Dehradun Defence Academy for being an important part of my journey to clearing the NDA written examination and getting recommended by the 21 SSB Board, Bhopal. The academy provided me with the right guidance, disciplined training, and continuous encouragement throughout my preparation. The concise study material, regular tests, and expert mentoring helped me strengthen my concepts and improve my confidence. The SSB training played a vital role in developing my personality, communication skills, leadership qualities, and overall officer-like approach. I am especially grateful to Shashi Shekhar Sir, Colonel Anupam Sudan Sir, Colonel IPS Rana Sir, Colonel S. Pandey Sir, Saurabh Sir, and the entire DDA team for their constant support and valuable mentorship. I am also happy to share that I have been declared medically fit with no temporary rejection, making me fully eligible for NDA joining. I sincerely recommend Dehradun Defence Academy to every defence aspirant looking for quality guidance and the right direction to achieve success.

For the written nda examination I attended Dehradun defence academy classes where I could find things in very systematic way and the content of the subject books had everything which was asked in nda written examination . And most important things was weekly test of the topics taught in whole week that I personally found very beneficial from the perspective of continuous revision. Then again I attended SSB OG classes from the this academy and I got recommended from 2 afsb board mysore . For this I would really like to thank the academy without it this would have not been possible. The guidance and the ssb classes were arranged and things were taught by Shashi sir that really helped me in evaluating myself and motivated me for the continuous improvement... Once again thank you Dehradun defence academy

I express my deepest gratitude to Dehradun Defence Academy for the pivotal role it played in my successful recommendation from 19 SSB Board, Prayagraj on 10 January. The academy’s structured, realistic and officer-oriented training brought a profound transformation in my personality, confidence, clarity of thought and behavioural conduct — qualities that are fundamental to an aspiring officer. I am especially thankful to Shashi Shekhar Sir, Colonel Anupam Sudan Sir, Colonel IPS Rana Sir, Colonel S. Pandey Sir, and the entire panel of assessors and mentors whose disciplined mentorship and precise feedback refined my communication skills, leadership attitude, emotional stability and performance across all SSB dimensions. I also extend my sincere appreciation to the DDA mentors, the administration, and Saurabh Sir for creating a professional, motivating and growth-oriented environment. I am proud to share that I am medically fit with no temporary rejection, making me fully eligible for NDA joining. This success stands as a testament to DDA’s excellence and commitment. With sincere respect and gratitude, Baibhav

I joined Dehradun Defence Academy in April 2025 to prepare for the CDS examination. The teachers were extremely supportive and provided strong conceptual clarity, which helped me clear the exam with just six months of preparation. Later, I enrolled in the 14-day SSB OG capsule, which gave me a clear and practical understanding of the SSB process. I would especially like to thank Shashi Sir, who led the SSB classes and gave individual attention to every student. Based on my personal experience, I would confidently recommend Dehradun Defence Academy to any defence aspirant without any hesitation.

Dehradun Defence Academy and SSB OG played a significant role in helping me clear the AFCAT exam and get recommended in the SSB on my first attempt. The 15-day SSB program was well-structured and highly effective in identifying and improving my strengths and weaknesses. I was recommended from 3 AFSB Gandhinagar, and I sincerely thank AC Shekhar Sir who helped me in bringing best thought out of myself, evolving my TAT stories and in building confidence. The academy's personalized attention to each student contributed greatly to my overall improvement and success. I highly recommend Dehradun Defence Academy and SSB OG to serious defence aspirants.

My journey over the last four years has been nothing short of a roller-coaster. I came here with the dream of clearing the NDA, faced failures in my written exams, and today I proudly stand with a recommendation. Every challenge—be it academics, sports, co-curricular activities, group discussions, or lecturettes—helped shape me into who I am today. What made this journey truly special was the constant guidance and support of the Dehradun defence academy faculty, which always felt like a family standing by me. These four years have given me not only success but also lifelong memories and invaluable lessons. At last, I would recommend every aspirant to be a part of SSB OG, because this academy not only prepares you for success but also gives you a family to walk with on the journey and "Special thanks to Saurabh Sir and Shashi Sir for their constant guidance and support, which played a crucial role in helping me crack the SSB."
