You will gather myriads of papers but, without guidance and expert advice you won't be able to crack MBA. here is the interview of CAT Topper Akash Gupta who scored 99.94 percentile. Here is what he says about preparation strategy for exams
PIs are very dynamic in nature. You cannot predict beforehand in which direction it will go. But broadly the areas I focused on as a part of PI preparation were- graduation subjects, curricular and extracurricular activities, current affairs, hobbies, family and hometown background, history of the current city and state and then there were HR questions as well like- why MBA? What are your short term and long term goals? Etc. Work experience is also an area from where questions are asked, but being a fresher, I did not need to worry about it.
As far as WATs are concerned, the topic could be anything. I made three broad categories of the topics- Abstract, Contemporary and Generic and wrote at least 1 essay on the topics belonging to each of these topics. Apart from that, I and my friends used to have frequent GD sessions where we used to discuss these topics. Though GDs are not part of the admission process anymore, except IIM L, the discussion provided us with beautiful insights into the various topics we discussed.
