We had 2100B today, same format as 2100A.
I don’t know (and am too lazy to check) if the notes we use are available to those outside the PTO, but we have what amounts to a highly condensed MPEP that we use to provide us with the “highlights” for the certification exam. An examiner prepared these notes, chapter by chapter, when he was studying for the sig test. They’re great notes, and they usually do hit the salient points well.
I’m not so sure how well they transfer to a lecture format, but they are very helpful to get a quick overview of a chapter in the MPEP, and to get familiar with what can be found in each chapter.
