I am a graduate in BBA. What should I do next among pursuing regular MBA and doing and job along with MBA?

Of course its better to go for a regular MBA Program

Best suggestion will be to pursue regular MBA. All the best

My suggestion would be straight go for MBA.if you don't get admission in a top ranked college ,then pick up a job and next year reappear for CAT to seek admission in top college. as an option you could work for a couple of years and then also go in for an eMBA program from one of the top ranked coll
