That depends on the school policies. The answer is Yes for most.
Any clue about INSEADs policy?
This is what their website states
"Can I apply before taking the GMAT?
No. We will begin reviewing your application only when all supporting documents have been received, including your GMAT score. However, we will review your application before receiving your official GMAT results, as long as you provide us with a copy of your 'Unofficial Score Report'. We will accept your 'Unofficial Score Report' as late as 23:59 Central European Time (GMT + 1) on the day of the deadline. Please note that no final decision will be communicated before receiving your official test score report."
If I select INSEAD as one of the schools I send my report to on the test date will that count as my "unofficial score report"?
