You can read and do objectives from Bengali publications like chaya prakashani. They contain enough theory knowledge and the objectives are quite relevant and accurate. You may also find NEET Question papers in Bengali but just 2 years only will be there.

Its better to join or take mock papers available in Bengali for preparation. The rest is same.i would also highly recommend you to read NCERT English if you are comfortable with it because direct questions are picked up from the book.
