IIM Bangalore - Indian Institute of Management

Going for MBA can have two directions, one you can pursue MBA as a fresher and work or two you gain some work experience and later, figure out what to do. If you want to go the first way, I believe you should appear for CAT 19/20, and check what is your current status compared to other aspirants around the country. It will give you a rough idea of where you stand. You have around 5 months which is good enough for you to prepare. If it doesn't work, you can get some experience a year or two and then try for CAT once simultaneously. So basically its a question you need to ask yourself. But whatever it is, I would recommend you to definitely appear for CAT 19.
