Hi Kishan,
It's not the case, however, being from a good college would mean that you have already been in the best environments and have learned quite a lot from your time there.

Dear Rajiv,
For Executive- Post Graduate Program in Management at IIMB. Yes, you need to have submit your valid GMAT/GRE (CAT is not necessary) for admission. However, this is not the only criteria, apart from the GMAT score, you should to have at least 5 years of managerial work experience (not more than 12 years). Along with your GMAT score, you have to give 2 LORs, SOP followed by written test and personal interview.

Dear Tushar,
It's indeed a great and valid question. To clear you, there is no particular answer for this question because it all depends upon to university to which you are applying. Ideally, family business is counted as your experience but you need to specify your job profile, working responsibility, salary and remuneration.
Most importantly, you need to give LoRs from your seniors and you must have to justify them that how this 'family business experience' helps you to gain the practical exposure of what you have learn in classroom and yes, good GMAT score (750+) will helps you in this journey.

Dear Anurag,
Considering your existing score and your work experience, you can go for GMAT and pursue a degree from any good college in India. Any score above 650 is good and any score above 700 can fetch you a good college in India.
Good luck.
