Hi, I am working professional with B.Tech, M.Tech degrees in engineering and 3.6+ yrs exp in India and 6 months exp in US. I got very less score 550 in GMAT and this was without a descent preparation. I am aiming to get into ISB ( probably IIMs for executive programs) and I am really convinced to take the test one more time looking for 700+. As my first score was not competitive, would that blow up my eligibility or consideration by ISB or IIMs even if I score 700+ second time.
Thanks for caring a reply
