Yes, you can apply for IGNOU etc. if you want to.

Jain College is no longer offering MBA in logistics and SCM under Bharathidasan University, but it does offer the specialisation in CMS B-School.

It's good enough. The University has a good reputation and a large alumni base.

You have already done your Bachelor's. There's no point in doing it again. That too, in relatively the same programme with different specialisations. Try to get into a Masters program atleast.
