Hey srotoswini,

Sorry, but its difficult to get admission on 186 provisional merit list rank. Because the seat matrix is like this,

General. 36

SC. 16

ST. 4

OBC A. 7

OBC B. 5

PD. 4

You can try for other good Colleges like St. Xaviers, Scottish, bethune, assutosh college and more.

Hope you found this useful

All the best
