@rockin skull: listen buddy , i can understand ur frustration of not clearing the GD round twice and u would nt wanna miss up an opportunity of not securing a job with an airline in this current scenario..
I also was unsuccessful in my first shot at GD, i thought i did well but they felt otherwise and the second time around i cleared it .. so to be honest please do not spend your money on some classes for GD as they cannot prepare you for that particular day.. I inquired from some people working for the airline and they said tht we are looking for basic qualities.. Leadership, presence of mind, power to convince someone and so on...
My advice would be not to spend money on some classes.. its ur wish after all..All the best for your GD.. cheers!!!
