. I'm pretty sure that in terms of content it's the same course as the book set, and the fill-in-the-blank and translation exercises probably work on-screen more or less as they do on paper; I'm wondering specifically about how the software manages the second wave, whether each lesson after the 50th automatically links you back to the corresponding second wave lesson or whether you have to scroll through and whether users type in their back translation which the software then checks against the original or whether it works in some other way. Any info much appreciated!
