hello,

Congratulations first of all forgetting such an amazing score in GMAT!!

Now, as for your Admission in MBA degree, your work experience will help you alot with your application by strengthening it. But I'm not quite sure of your percentage because the colleges you mentioned have a very low acceptance rate and their eligibility criteria demands atleast an 80% above overall standing in exams.

As for your GMAT scores, average GMAT score for LBS is 708, for Yale is 721 with an acceptance rate of 25% and average score for cambridge is between 687 - 700.

All in all, you really should put in your application, if it works out you might even he eligible for scholarships !

Good luck!!
