Do you think that it is necessary to take classes for CAT & XAT, or just having the study material is enough?
Answer: It is always better to take the classes because then you are not only competing with yourself but also your batch mates and get involved in a lot of brain-storming sessions. Studying on your own would require a great deal of commitment and determination on your part. Secondly, you will only be able to gauge your performance and not have a comparative parameter to judge your improvement.
