Now, after your thorough prognosis and diagnosis, kindly answer these questions of mine:
1.) Is there even a remote possibility of me getting any of the top 5 college (Rank according to FT) ?
2.) Should I be too worried for my low CGPA. and is there anything that I can do to compensate it now ?
3.) When, according to you is the right time for me to apply ?
4.) MBA from US or MIM from Europe? Please note that I come from an Indian lower middle class family, so I need to be extremely sure about the decision that I make and the Return on Investment. The MBA fees of top US colleges is like my father's 15 years of net salary, that too when I assume that he was getting the same amount in 2002 as in 2017.

Thanks in Advance. Please Reply Soon.
