M.A Economics

Hi Naina,
Master of Arts in Economics or MA Economics is a 2-year full-time or distance learning post-graduation programme to sharpen student's dexterity in areas of finance and management. The minimum eligibility criterion required for Master's degree is 50% aggregate in Bachelor's degree in any discipline. So yes, you are very much eligible for the course.
Some of the top institutes offering the course are:
Loyola College, Chennai
Christ University, Bangalore
Presidency College, Chennai
Miranda House College, New Delhi
Lady Shri Ram College for Women, New Delhi.

Better to go for MBA as it will open a number of opportunities not only in economics but also in the field of finance, marketing, operations, HR. There are numerous opportunities in these fields. You will get ample amount of opportunities to work in your field of interest. You can test yourself with fields like investment banking, relationship manager, risk analyst, brand manager, strategy manager, product research analyst, consultant and many more. So, in my view from a career and job prospective MBA is a better option.

The entrance examination consists of objective type questions. This is designed to test the candidates general aptitude (including his /her quantitative ability) and understanding of economics at Bachelors level.

Sorry, it would not be possible to complete the 2-year programme in one sitting. There are hardly any colleges which are having such provision.
