Hi reyvanth

You can not write CAT exam right after your 12th exams. You need to be at least in the final year of your graduation to attempt the CAT exam. Assuming that you are going to go for MBA after graduation, I would suggest you choose your graduation carefully as your graduation marks will affect your MBA admission process too. Also, make it a habit to start reading articles and news papers everyday. So when you are finally preparing for CAT you are good at Verbal Ability section.
