I've enjoyed the study so far and started it nearly two weeks after she started her week-day broadcasts. You can watch the broadcasts at LightSource.com where this feed originates, so you can catch up with her or take the study at your own pace.
If you go to Kay's homepage, http://wwww.preceptsforlife.com, you'll be able to get to a source to download the .pdf study guide for free and also have access to .mp3 files for each broadcast.
I hope you enjoy it as much as I have. :)
