This coaching is the first choice of mine and I got it right. The psychologist was good, had a vast experience of 8 years taught me in a very clear way. GTO sir was friendly and taught all the tasks. And finally, the interviewing officer taught me all my weaknesses and strengths.
One of the best coaching institute in defence preparation sector, provides the best facilities and support to the students. This is is my personal experience as I am selected in Indian navy through the efforts of the DDA team.
This coaching institute has the best teaching and staff one can ask for. In a span of 6 months, I did my NAVY (AA &SSR) coaching for NAVY(AA&SSR) paper and clear the paper. Thanks to the fellow teaching staff for helping me to achieve my Dreams.
I came here for SSB interview Coaching. The teachers are very friendly. They teach us content-wise what I wanted. They say not to remember any WATs and SRTs but they guide us what type sentences are considered good not bad. Nice and Affordable.
