Hi arjsrivastav,
The process of working on your applications (taking the GMAT, essay writing, etc.) and ultimately attending Business School requires a substantial amount of time, money and effort on your part, so it's important to really think about what YOU want out of your degree. If a deferred Program is one of your priorities, then you can certainly work with that goal in mind. However, if you have a strong GMAT score and earn a couple of years of solid work experience, then you could apply to pretty much ANY Program in a few years time.
Is there any particular reason why you're thinking about deferred Programs?
