Yes, BA honours in major economics is available in this campus.

I don't think so that the college will allow you to take admission in the final year. However, I would suggest you contact the college officials for more clarity.
Admission is possible only if you get a NOC from your current university.

Hi,

After your graduation from a recognised university, you are eligible to join the Diploma programme under distance Education Mode of selection. You shall submit an application in the prescribed form along with required testimonials. Application forms are issued in the 1st week of May.
All the best.

Yes, you can get admission in Diploma after your 10th. Now from this year Diploma is equivalent to 10+2 and in future if you want to do further studies with same branch you'll get lateral entry mean direct admission in second year.

There is no separate form issued by the college for MSW. Once you have filled the application form, you will be shortlisted and thereafter called for admission and at the same time entrance test is conducted.

I prefer you to complete MBA for good package, because you have an experience.
