amordiva on "Becker's Final Review Materials"

For each part, it costs $165.
I want to hear feedback from those who already bought and used it.
Guys, how this did final review help you in your actual test? How many hours are needed to finish this material?
When I inquired from Becker's customer service on the phone, I was told I would need a day to finish this final review. This final review doesn't come with any practice final tests or something.
I got less than a week left before my scheduled test on 8/1.
