@CannedMan I learned Latin from Oulton's three books, and the accompanying, "Latin Translations" by Betty Halifax. The first two cover the basics; book III, all the difficult stuff. Each has an associated answer book; but only the book III one is necessary. I am not familiar with this "Revision Guide", but if it's as good as his other material it will be worth the buying. He also does online lectures (free) so you can actually get to see him!
