from the INSEAD website:
Can I defer admission?
In the large majority of cases, no. You should apply for the intake in which you intend to enrol. In truly exceptional circumstances, the Admissions Committee may grant a deferral. All requests should be made in writing and will be reviewed on a case by case basis.
Have you decided what you'll do?
Thanks for the information. I have read that before but it's still hard to get a sense on how hard it would be to obtain a deferral in my case. My thinking is to receive the offer first before making a decision on it.
I don't want to comment on INSEAD's deferral policy, as I have no experience.
But have you thought about doing a pre-mba internship? It will be a solid substitute for the december intake's internship option
