What are the benefits of CAT ? How will CAT help me in making my future?

Appearing for CAT opens doors for MBA courses in India (and few abroad as well). But if you can crack CAT, you can easily crack GMAT as well (which clears out more avenues). But yeah, majorly concentrated for business schools. And these scores play a huge part in the selection process. So I would say there's definitely no harm in trying for CAT. The syllabus is also generic and interesting to learn. But taking out time in already busy life is something that people struggle with.
