Hi! I am a mechanical engineer 2009 pass out from SRM university in chennai.I have been working since ma UG at my dads firm which manufactures automobile components for OEM'S such as ROYAL ENFIELD,HYUNDAI etc...had given my heart and soul to the same and the end of two years of my work ex we started a separate firm for some of our customers with devoted manufacturing lines.I am the head at new plant since past one year since its start.There have been many major achievments in my 3 and half years of work ex including passing some tough customer audits and important recognitions,awards and certifications.I was equally involved in the technical and managerial aspects of the plant.I have been wanting to pursue an MBA for better managerial skills which i feel i lack at times strictly required by the industry.have given trials at gmat but te score din do justice to either my capability or my effort because i had given lots and lots of mock tests( official,mgmat,kaplan etc..) and din score below 660 in any of the cases but always ended up messing up my real gmat. Im in touch confusion if i should apply with my last score or should give an other attempt bcoz all my scores would be reported if at all i end up with an gud score next time. will my profile help me to get through with a score 600??? any advice would be appreciated.
