You got a good GMAt score.

yaar champ. this TRU pre-MBA seems doubtfull, because of credibility of University.
unfortunately you don't have 16 year education.
You can-
(1) Complete 1 year PG diploma in business in INDIA and apply again into direct MBA in above average university.
(2) Take PG course in canada. yaar atleast better than TRU pre-MBA (atleast i think so)
I am not sure about International MBA @ Trinity western university wheather they accepts 3 year degree or not. Also check out it.
however TWU is dam expensive (iMBA = 34000CAD tution only)
