hi, if you're struggling a few months later with texts that you've already worked through, then i suggest you try an exercise of determining what exactly is making you stall on the re-read.
over on the greek side i talked about this (see the second post here: http://www.textkit.com/greek-latin-foru ... hp?t=11778
) and so while the texts etc. that i mention there aren't relevant to latin, i think it could still be helpful for you to try the exercise of working out exactly what is making you stall on a re-read (e.g. vocab? something else?) and then work on that specifically.
also on the greek side there were later very helpful posts by markos and others pointing out something i missed, that sometimes these factors alone aren't an issue but in combination they can overwhelm causing your brain to crash. that you could also work on methodically too, getting a better grasp of each part so that the whole is not so daunting to a brain trying to grasp everything on the fly while reading.
if you try one of these approaches and it helps, it would be great if you could let others know as i'm sure you're not the only one having this difficulty! cheers, chad
