Hello,
Yes no such rule is there and you can pursue mbbs from bangladesh even after 2 drop years.

However you should know that after completing your mbbs from bangladesh you'd have to clear an fmge exam  for getting a license to work in india and do a 1year compulsory internship in india.

You can use careers360 college predictor to know the colleges you can get at your NEET score:- https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer
