the uni textbook's not too bad actually (jones&sidwell), though not as friendly as the distance ed. handbook.
You *can* do 3/4 through distance ed without doing 1/2, someone in my philo class is doing that now. but they've done some latin before and had 'come up to speed'. I've done 1-4 through distance ed and the uni course, and i preferred the uni course. better to get it over and done with in 7 weeks than worry about sacs and deadlines, and worksets etc. otoh, you don't get the scansion and metalanguage for poetic techniques in the uni course.
And yes, to azureblue, latin does help with englang, but you don't need it. i got the same score as someone in my class who didn't do latin.
