Ask Admissionado

hi,
I am a 34 yr old female with 1year as a lecturer in Civil engg, 6 months in a structural design studion, 8 yrs in IT, (3 as a programmer 5 as a Business systems analyst). Have been thinking of MBA for long now, first attempt was 570 (hasty attempt, with anxiety attack)..
preparing again now after a gap of 4 years. BE-Civil engg(3.0gpa) ME-str engg(3.5 gpa). my profile is pretty weird as moved to IT post engineering as the Engg opp weren't that interesting.i have a gap of 1.5 years on my resume (baby mid 2012-current)I am planning to join back but first I want to get a good score in gmat.
my target schools are Insead or ISB india and will apply in 2014 R1.
what should be my ideal score? and do you think I can get into INSEAD?

Thanks! what additional information do you need?
