Hello , 

As per your question, i would say that the registration dates are not fixed for bsc nursing. Just having a idea, most probably it will start after the neet exam and after your boards exam are over.  Basically the tentative dates after the neet exam that is after may month. Basically, check their official site for the exact dates and information.

Criteria is- you have to Passe 10+2 examinations with Physics, Chemistry, Mathematics and English.

And Admissions to the B.Sc (Nursing) program is done on the basis of marks scored in 10+2 level.
