UPDATE: According to Chris Barry , the instructor in these pod casts, Salesforce has removed them because they are now focusing on new/better low cost training. As soon as I learn more about what that is, I will post about it here.
For anyone studying for the Salesforce Advanced Developer Certification, I strongly suggest you check out the following recently refreshed series of Podcasts posted on ITunes. They are recorded sessions of a fairly recent (from the Spring 2013 time frame) class given by Chris Barry at Salesforce.
There are some differences between the online premier training and the in-class training, but for the most part, you could follow the notes posted on this blog as you watch the Podcasts. Just keep mind that the episode about the Developer Console is very out of date, since the Developer Console has changed dramatically in the Summer release.
