#6-Target schools
Post MBA career goal - Consulting.
I applied to Booth, Kellogg, MIT, Columbia and Wharton in 2012, and I was dinged by all of them. Hence, I thought of improving the GMAT. I am hearing mixed reviews. Some people say that I need to push the GMAT above 750. Is that true?

Target schools for this year - Booth (I interviewed at Booth), INSEAD, Haas, Stern ..(any other school?)

I am open to your thoughts, suggestions and expert guidance. I would appreciate your help. IF you need any additional details, please let me know. I hope that I haven't exceed 500 word limit specified by you
