What is the scope of marketing management and retail business course? Can I pursue MBA after completing this course?

Its better to go for MBA in retail or marketing then doing some course and then MBA. MBA is a good course. Best of luck.

Retail business in India is still growing. Many MNCs are there to enter in India. As far as this specialization is concerned, you don't need to worry as plenty of jobs are there. You can go ahead. All the best.
