Why the books don’t match up perfectly with the videos
The Kaplan Books, Princeton Books, and Khan Academy Videos were all produced by different authors. For this reason, there are some chapters in the Kaplan Book or Princeton Book that are not even found in the Khan Academy Videos and vice versa. For instance, the Kaplan and Princeton Books have chapters that cover certain experimental procedures that the Khan Academy Videos do not cover.
Our goal in matching up the books with the videos was to correlate the content as best as possible while also covering ALL the content from every resource. For this reason, when nothing in the Kaplan Books matched up with one of the video playlists, instead of leaving the reading assignment for Kaplan blank, we inserted material that did not fit in anywhere else (i.e. one of those chapters on an experimental procedure that was not covered by Khan Academy). So, when the assignment doesn’t appear to match up right, please know that this was intentional.
In summary we tried very hard to match everything up perfectly, but that simply was not possible. They are lined up fairly well and if you follow the reading assignments outlined, you would finish the entire Kaplan 7-book series and/or Princeton 7-book series by the time you finish all 10 content modules.
Why the sections in your book don’t always match up with the sections outlined
Another cause for confusion may be that the sections assigned in our eCourse do not match up with the sections contained in your content review book. For instance, your version of the Kaplan Biology Book may not have a section 10.4. This is due to the fact that we used a different edition of the Kaplan books when matching up the videos to the sections in the content review books. They should match up the large majority of the time, but in the rare instance that they don’t, I’d recommend simply reading sections that do match up and saving the ones that do not for a future lesson that more directly relates to the topics in that section.
Here are the books we used during the original matching. We plan to stick with these older editions of the books since little changes between editions and the older editions are much more affordable:
