Hi madgmat2019,
Depending on how big the differences in the names are - and if there is no way to 'fix' that the names on the various documents will not be an exact match - then this will probably require that you go through some extra steps when you send in your applications.
When names don't match up, the logical question for an Admissions Officer to ask would be "is this applicant the same person who took the GMAT?" In general, you don't want anyone in Admissions questioning any part of your application - BUT if you provide plenty of documentation for why the names are not an exact match, then you might be fine.
This is ultimately an Admissions question, so you would likely find it beneficial to speak with an Admissions Expert about this issue, your overall profile and plans. There's a Forum full of those Experts here:
