My questions:

1. Do you think I should retake the GMAT ? Specially as my score is quite imbalanced. I am sure I can improve 30-40 point on this, but wanted to see if giving up first round deadlines for GMAT retake is worth it ?

2. I am thinking of applying to MIT, INSEAD and HBS . Could you please give me an assessment of my profile ? Also would you suggest any other Tier 1 school for my profile and career goals ?
