I did some digging around to see how different organizations are responding. A few findings:
* Apply without a GMAT score
for nowA part of an email one of my students received from INSEAD:
"
We encourage you to continue to prepare and finalise your application without test scores if you are living in a country affected by test centre closures. The admissions teams will start evaluating applications without GMAT, GRE, EA or TOEFL test scores while waiting for the test centres to reopen. They will advise you on the options available to enable you to provide a completed application.
"
* Take the GMAT later,
if needed"We reserve the right to request a GRE or GMAT test score if the selector is unable to make a decision on your application without this information." - LSE website
* Apparently, ETS is working on an "
at home" GRE solution (
