Beat The GMAT a GMAT & MBA community

Hi there,

I am a final year B.E. student from Delhi, India doing my Engineering in Polymer Science and Chemical Technology from Delhi College of Engineering (one of the top 10 engineering colleges in India).
I recently gave the GMAT on April 24, 2012 and got a total score of 740 (97th percentile) with 50 in QA (92nd percentile) and 40 in VA (89th percentile).
Before typing in any information which gives details about me, I guess it would be better to post my Resume, as it would probably give you a fair idea about my profile.
The biggest issue bugging me at this point of time is the absence of GPA system in my college (we are just given a percentage at the end of each of our 8 semesters), so please give me a workaround for this problem.
If I go for an MBA, my preference would be ISB-India, Duke, Chicago Booth; basically any college in the top 25 list from Financial Times (http://rankings.ft.com/businessschoolrankings/global-mba-rankings-2012) would do.
Also, I have absolutely no problem with MIM courses, especially the ones in top B-schools in Europe, such as HEC, ESCP, Insead, LBS, LSE, etc. On the other hand, I am really starting to like the idea of going to HEC or ESCP or Insead for an MIM!!!
Please evaluate my profile and guide me as to what course of action I should take: Should I wait for 2-3 years work experience and then apply for MBA OR start applying this year itself for MIM courses?
Please ask for any information that you feel is missing in my Resume, and I will be prompt to reply.

Thanks in advance!
