MBA/GMAT for 7+ experience - Is it worth ?

Need your views on my very basic queries on MBA and GMAT. 

I am an IT Consultant with 7.5 years of experience and working in Germany for the past 5 years. I am evaluating if a MBA degree at this point coulld give a boost to my career growth.

I am preparing for the GMAT already and  would prefer a 1 year full time executive MBA in INDIA.  Please let me know if taking a break and going for an MBA would be a wise decision. 

How much I must score to get into a top Indian school  ?

Looking for Suggestions and views of pursuing 1 year executive MBA for candidates having 7+ years of experience.
