Roddie's information on what he did to prepare for his recent Oral and Practical exam might be of help.

I endorse this message, though the author is suspect ;-)
I did do the webinar that you're asking about, and he basically goes through 15 questions that you're "guaranteed" to face on the oral in what is supposed to be a "live" webinar session.
Here's my feedback on it (YMMV):
- He presents each question, waits for everyone to "submit" their answers (see below), and then gives the answer with a short explanation.
- I think I hit maybe five or six of the questions on my actual checkride, which were already covered in the Youtube video above along with the ASA book.
- The session itself felt previously recorded and not live. I don't have any proof of this, but my real life work involves attending WebEx presentations daily, and this one just felt canned. Ultimately, it doesn't matter, the material is what it is and was covered.
- At the start of the session you're promised some bonuses for sticking through to the end, including an "advanced" copy of his book (+ audio), and MP3 recording of an actual oral exam, a transcription of the flight portion of a checkride, and "The Checkride Blueprint", claimed as $550+ worth of material.
- At the end of the session, you find out that these bonuses come only after joining his Online Ground School for $27/month.
- All that said, it's $5 (it was $10 when I did it) for an hour or so of relevant aviation talk, so I wouldn't call it a waste. You're emailed a link to the "recording" for later viewing, so again, not a bad thing.
Hope this helps!
