How is CAT for me

To know basic information

Hi everyone... I have a confusion please suggest me what should do ... I have done highschool with 59.50%, +2 with 69%, and engineering in instrumentation & control with 71% .now i have 4year of experience in process industries as instrumentation engineer .but now i was thinking for CAT preparation so should i do it? Will it be good for my career ? Why i am asking bcz in some forum i came read that who have 3-4 year work experience and have academic score less than 75 % will not be as good to do mba even from iim and just places below package of 10 LPA is it right ? Please suggest me ..
