CAT

Hi, yes you are eligible for CAT. You just need to do a planned study in math since you feel you are weak in that subject. Being an experienced person in the same field I would like to suggest you to solve practice question papers as many as you can, this will help you in scoring and accuracy in your answer.
Good Luck.
