Dear Pooja,
If you want to learn foreign language then go for regular or weekend mode because through that you can understand the concept, culture and pronunciation better.
For that you can go to Cervantes de, Delhi in CP which is an affiliated college of embassy and gives you the right tools to learn in and they also have a weekend batch.
All the best.

Yes, they are accredited and affiliated courses.

MBA, whether full time or distance, can be considered to be a good choice if pursued from one of the top colleges. As Sweta has mentioned, you may first get some work experience in order to figure out what you really want to do. However, if you have a leaning towards marketing, do not work for more than a year as companies generally prefer freshers or people with low work experience for marketing roles.

Indira Gandhi open University will be a good option since you said you are financially not strong.
