Leave job for CAT preparation or not ??

Hi Everyone ,

My question : Leave job for CAT Study OR Study with job. ?????

I am aiming for CAT 2013 , Currently I am working with IBM since 2 years and I want to do MBA. This 2013 is my last chance to do MBA So should I take risk of leaving job and study for CAT ?? or continue job with study.

I have given 2012 CAT with 25 days of full study and results are very very bad 😔

So I need suggestions , Advise anything that will help me decide whats better option for me.

Thank you..!!!
