I've made it to XXXII so I'm getting there. I'm sure you are moving ahead as well, but I hope to be caught up within a week or so. I work very long days, so most of my study is confined to the weekends. On the other hand, I have Fridays, Saturdays, and Sundays off, so I can get more done on the weekends. It all evens out. I've been struggling a bit but most of my answers have been correct when I check them against the key. The deeper I get into the book, the more I enjoy it.
