Hi,
Since there are hardly any posts on GMAC accommodations ,I would like to share my experience on the same and try and help others who are out there.
GMAC does provide Testing accomodation to those out there who fall under the categories specified on the mba.com site.
You need to make sure your Doctor reads through the guidelines so that you meet the GMAC criteria.
If you are a valid case .I can vouch GMAC will do everything to provide you with relevant support.
I recently received accommodation by GMAC and Kudos to my doctor and specified guidelines by GMAC which helped me get accommodation in 25 days flat.
Some points to note.
1.You can only Fax/mail the accommodation.They are confidential medical documents and thus GMAC does not accept emailed/scanned copies.
2.After faxing the copies and the form,GMAC will revert with a receipt of acknowledgement within 2-3 days.
3.There no point or need to call GMAC for decision as the decision is emailed or a letter is mailed to you accordingly about the decision.
4.I sent my documents via fax.
5.After receiving accommodation decision you can activate accommodated setting on the GMAT prep by entering the accommodation code.
I largely recommend every one who is suffering from one of the ailments listed on mba.com webiste to try for GMAC Accomodation as it is indeed a boon for you.
