What I liked most was the vibe, the kind of environment one needs to keep motivated. The study material helped me a lot, not like those overly complicated textbooks that make your head spin. They covered everything we needed without the unnecessary crowding of topics. Also mock tests were a game-changer for me. Helped me figure out where I stood and got me used to the ticking clock. Plus, the practice interviews were a nice touch—they weren’t kidding about prepping us for the real deal. In a nutshell, if you’re eyeing the NDA, Centurion knows how to get you there.
