Strictly speaking, its difficult to gauge the cutoffs of various colleges for candidates of reserved categories, especially NT. Just for the simple reason that the seats are very less in these categories. So even if you score 140/200 and there are two other candidates who have scored 140 +, your chances to get into JBIMS are doomed, despite the fact that 140 is not a bad score by any means for a reserved category candidate.. So stop worrying at the moment if you would make it to the institute of your choice or not, and start preparing for the GDPI...
P.S. I , probably, know the two guys who would make it to JBIMS under the NT1 (Home University) category.
