Did PMI not send you an email where they say that your application has been approved and that you can schedule the exam? I believe that is what they are referring to. Check that email it should say something along those lines in it.
I've just found out I need to present a PMI letter at the testing center. Have I missed something fundamental here? Don't have any letter as I thought I only need to present 2 forms of ID. Any guidance wil be appreciated. My exam is in a day. Thank you
