Part Time MBA

Yes, it will always be an addition to your career growth, if you pursue MBA along with your work experience of 3.5 years.

JBIMS is for learning and IGNOU is for distance education.
Don't go for other colleges.

For working professionals, PGDM is better choice than MBA. PGDM is also more prioritized than MBA if you have proper experience to present along. Since you are already working PGDM will be better for you.

Part-time MBA for working professional is available in certain institutes so that those who want to earn PG degrees can actually complete it in the normal course.

NMIMS is one of the most reputed institute in India. Yes, it has attendance criteria but it offers you real return in terms of quality education. So, you can go ahead in MBA in Finance.

Sikkim Manipal University and Amity University offer MBA programme through distance mode. Also, IGNOU offers MBA too. But in my opinion, SMU will be easier to pursue, because it is very flexible for working people.

This would depend a lot on your financial status. If you don't have financial responsibility, then you should pursue full time MBA from a top ranked institute and you have responsibility to run a family then an Executive MBA or part-time or distance MBA is a preferred option.

Nowadays, a lot of options are available for candidates who want to pursue MBA while working. You could explore the following:
1. Part-time MBA
2. Executive MBA
3. Correspondence MBA
4. Take a sabbatical from your current employer and enrol for the full-time MBA.
Full-time MBA colleges do permit you towards the 4th semester. However, for the first three semesters, one needs to attend college full-time.
