Distance/Correspondence

Of course, you can pursue M.Sc in nursing after completing B.Sc in nursing. In fact, many colleges would prefer a B.Sc in nursing graduate as they are already familiar with the basics.
Thank you.

Please refer to the link mentioned below for the list of colleges which offer M.Sc through correspondence or distance:

Most of the universities which offer MBA by distance learning conduct interactive classes during weekend either in physical or web classes.

Yes, you are eligible. But you must score 50% marks in your graduation.

For correspondence MBA, you should go for a govt. university. IGNOU is the best option.

For managerial skills and management skills if you are looking for please take on MBA which will really help you. If you want to improve your technical skills then Diploma in Mechanical.

Dear Suman,
Not just in India, but in the entire world, you can never do engineering and medical through distance mode. So don't ask for B.Tech college in distance mode in Kolkata as you will not find and even if any college offers B.Tech in correspondence, means they are violating the rules of AICTE. Go and complaint them. So, go for regular B.Tech program.
Ask any query at anytime.
Good day.
