Your chances are very low. 

As there are only 320 seats for 3 yr law course in glc out of which 50% seats are reserved, there are only 160 seats for the general category students. Given that GLC and ILS are the top 2 colleges in Maharshtra, all the students who have scored well would opt for GLC or ILS. So even if about 200-250 students have scored more than you, your chances would become difficult and given that the exam was actually very easy, i think that more than 500-1000 students would have scored above 100. However, dont get disappointed and hope for the best as you could get lucky any time. 

Very low chances to be honest based on your marks and considering you are from open category. Its probably better you look for other options at hand.

All the best!
