My suggestion:
DO NOT, i repeat DO NOT (!!!) APPLY FOR THE OAT ONLINE!!!!!!
Big Mistake!!!
They will take your money and WILL NOT SEND YOU THE TICKET!! Happened to me when i took my OAT back in October 2003. When i called the them, they said they didn't receive any of my info, not even my SOCIAL SECURITY! ....YET, they charged my credit card $100.
I called them 4 days before the test date and they sent me a ticket. 1 week after the OAT, I had to send in a paper application and show them my bank statement.
Apply through paper only. Otherwise, you WILL be sorry.
😎 Just a friendly warning😀
