Hi sidhant mishra,
There are a number of 'variables' when considering which type of MBA program you might attend. Since these types of Programs require that you invest a great deal of time, money and effort, it's important to think through the details and how you'll work your life around attending School. That having been said, there are MBA programs that will allow you to continue working (full-time or part-time) while you're in School (full-time or part-time), so you have to research the various options and choose the one that best fits your overall goals.
Do you know which Schools interest you?
Have you taken the GMAT yet?
