This place is a total scam. The material doesn't help you and then they make it so difficult to speak to anyone that you end up just giving up. I don't even think they know what is on their own website. They advertise helping get people jobs at the post office but their terms and conditions say they get paid by giving opionions on consumer products/sites.
What in the heck does that have to do with getting me a job at the post office? I have been trying to reach someone for weeks and still no luck. Do not give these folks your time or money. It will be wasted and that is a guarantee.
