hello aspirant,

see it is not possible to do extra course with b.sc nursing , as you are doing a course in graduation. however if you think you are not getting interest in b.sc nursing you can leave and join some other course. however you need to find your real interest. see you have not mention which year you have passed your 10+2 exam, but you can take least of 2 years gap after 10+2 which is allowed by all multinational and government exams. other than b.sc nursing bachelor in business administration , bachelor in hotel management course all are available.
