Hi,
I am attempting to access the online practice tests for the GRE for Dummies, but I am unable to do so as my pin is invalid. Please contact me at the e-mail address associated with this account so that this can be addressed.
Sarah
I'm sorry about that, Sarah--I have created a technical support case for you and will be emailing you directly to resolve this. Please, reply directly to that email with the requested information and I should be able to assist you.
Sincerely,
Tom with Wiley
