Oh. I guess it will be really difficult for me to not read ahead.
I did ponder on the idea of instead copying over the vocabulary week by week. (Too much hassle.)
I’d say you can use any free time to answer questions as come up, but typically by volume two of a series, most of the ABBC-level readers have dropped off (unfortunately). Hopefully we’ve still got a few hanging on, though, because volume two’s grammar usage nicely builds on top of volume one’s.
And speaking of, it’s never too late to review all the grammar in the week’s reading and see if there’s anything you’re not 100% sure of!
