I'm not sure why this is free right now, but one of my students noticed that the Kindle edition of Barron's AP CSA test prep IS FREE right now!
I know many CS teachers teach more than just one course, so I thought some of you might be teaching AP CSA too and might be interested... And/or you'd know others who might be.
(They also seem to have these subjects for free too: AP Statistics, AP Chemistry, AP Biology, AP Psychology, AP World History: Modern, AP European History, AP United States History, AND AP English Language and Composition.)
