Hii Aanchal..

As the minimum marks required  to get best colleges in Maharashtra.150 or even at 100 marks,student can also get admission in good college of Maharashtra on the basis of JEE Main marks.

I think there are some as around 15% .Which is filled on the basis of JEE  rank Of the aspirants.So if you are  outsider ,you may use your JEE  score to get good colleges.

As your marks is 81 in  MHT CET , which is not too good tt get best colleges, but there are some private colleges where you may try:-

1)LTJSS Priyadarshini Institute of Engineering.

2) Zeal college of engineering and Research.

3)SB Jain ,Nagpur.

4)Dy Patil ,Pune.

5)Ycce ,Nagpur.

Have patience and try till the last.

All the best!!
