Hi friends, like u even I wanna enter prestigious management institutions through CAT.for the paper I suggest long term planning not only through books but by developing fast, correct decision making and above all rational outlook.Such traits cannot be developed in one year as many people think rather it has to be developed from day one i.e today.also personality also needs to be toned.
This again cannot be achievd in one night or through books .Talking to different people and having , expressing your own opinion will help you go a long way.Coaching is important thuogh optional but it lets yuo know the level of the exam and ofcourse the type of competition you will be facing.
