Quite good and honestly, most non-Maharastra students tend to not take admissions beyond these 5–6 colleges. You may have to score in the range of 98%ile to 99.9 to get into some of these colleges.
There are fair chances of Non - Maharashtra students of getting the above-mentioned colleges under All India Category seats as per DTE Maharashtra for MS and PGDM programs. In colleges such as SIMSREE & PUMBA, more seats are reserved for students from Maharashtra as compared to seats for students from the All India category. You can refer to the DTE Maharashtra website for more information.
