Is MBA a better option than PGDM? I have completed my graduation.

Both are good. PGDM is an Institute autonomous program which is approved by AICTE. MBA is a program which is affiliated to a university. Colleges which offer AICTE approved courses will also offer PGDM not MBA, for example, XYZ College is affiliated to ABC University then it will offer MBA course af

Yes, MBA is better than PGDM in long term career goals. Although PGDM and MBA is equivalent but to start a career initially degree has more importance than diploma. You should go for MBA.
