Only first name

Hi ,

I have only my first name on all my legal documents, including my passport. Would that be an issue while registering for gmat?
What should i put into my last name while registering?

Your name should be entered exactly as it is written on your passport.

You should not experience any problems, as long as the personal data you enter, first (given) and last (family) names are in the proper order, date of birth, and country of citizenship, exactly match what appears on the identification (unexpired with signature) you will present at the test center.

When creating a profile on https://www.mba.com, if your passport book does not include your surname (family name), please enter a period/dot in that field.

Please see below for an example:

Either:
First name: Tonya
Middle: Michelle or leave blank if you do not have a middle name
Last (surname) name: .

Or:
Last (surname) name: .
First name: Tonya
Middle name: Michelle or leave blank if you do not have a middle name
