Hi,

From this question I gathered information that you are pursuing BSc ( you are in 3rd year) and want to go for BSc Nursing in Aiims.

Well yes of course you can pursue BSc nursing even after your graduation,if you are eligible for the exam

Eligibility criteria for Aiims Nursing: Minimum age limit: 17 years

You must have passed 10+2 Boards with 55% marks from a certified or recognized school or institution.

You will need to appear for the Aiims Bsc Nursing entrance exam on basis of that you'll be alloted college.
