I seem to be having better luck with Collins' Primer. As has been mentioned by previous posters, I am beginning to see how Scanlon is not well suited for self-study (I'm currently in the middle of chapter 3 of Scanlon). Collins' explanatory notes and especially the vocabulary notes are wonderful... and seem to suit my own personal style of learning (to each his own, I suppose). Scanlon seems to omit too much of what I have thus far found in Collins to be quite helpful. What say ye?
