I think you have an excellent score and a brilliant chance to get yourself into a top class business school.

A friend of mine got into INSEAD with a score of 720 without any problems, and he certainly doesn't match your other credentials

The difference between a 710 and a 730 is not statistically significant. It is also above the average for all but two or three schools. It will not be an issue with your application. Besides, taking the test three times, especially with such a strong score, will suggest to the admissions committee that you are focusing on the wrong thing.

Describing your professional career, what you have learned and what you will bring to the classroom will be far more important to establishing yourself as an attractive candidate. Your combination of consulting and pharma experience should be a great selling point. Be sure that you can clearly and convincingly articulate your career goals and why that particular school will contribute to your meeting those goals.

You are an excellent candidate. Good luck!
