Dear Neha,
There is way to much difference. There are 85% reserevation for Maharashtra candidates in Govt. and Govt. Aided institutes and 10% are for All India Candidates (OMS) in MH CET 5 year LLB. and in Unaided or self-financed programmes 15% seats are for OMS. Understand it with this example, if there are 180 seats in ILS Law College, Pune; if all MS candidates of MS Merit list choose ILS then last candidate who has scored 94 (not considering reservation given to MS SC/ST/OBC etc.) will get admission there. As there are only 18 (10% of 180) seats for OMS candidates, It means the last OMS candidate who will get a seat at ILS will have scroe of 116. I hope it helps!
