I faced the name match issue before, so I know how problematic this can be. I was about to register for the GMAT, but I paused a bit and looked into my passport. It's a bit different:
Passport:
S.M. Mahbub Murshed
(Does not tag/categorize different parts of the name)
Registration:
S M Mahbub Murshed
(First: S M Mahbub) (Middle:) (Last: MURSHED)
I tried to change it online, it won't let me do it. I created another account, it will need approval and may not be done in two days.
So I called the customer service to correct this problem. The person picked up the phone said it will not be a problem, since the difference is just the dots. When I asked, what do I do if the person in charge don't allow me to take the test? She checked with someone and reassured me.
But still I can't believe it, since the mba.com website says the name must match "exactly".
What do I do now? Wait for the second account to be active or register using the name without the dots?
