Hello aspirant,

No, it is not necessary to do BA in order to pursue MA.

The eligibility criteria for MA is

• Students must have completed graduation from a recognized institute or college in any discipline.
• Students must hold a bachelor’s degree with a minimum aggregate of 50 percent marks.
• Students must clear the entrance test with the required cutoff specified by the institute followed by the personal interview.

I hope this information helps you.
