I emailed Examunit about results of 6600 test and when to expect them and this is what they told me.
For Station Agent, Exam#6600, we are in the process of rating the Education and Experience Test Papers. IF you do net meet the qualifications as stated
in the Notice of Examination, You will receive a letter in the mail informing you that you were found "not Qualified" withering the next few months. If you were
found qualified, you will receive your letter of results when the list is established in about a year.
Just thought I would share the new with the rest. Good luck everyone.
