I bought this for my daughter because her high school went to "online" version of ?Avancemos! That was almost immediately a problem for her as it is hard to see the whole page on screen, etc. Most galling was having to sign a paper saying my child had internet access and we were happy with having an online text. The alternative was to drop language class if we wanted a paper textbook- unless she had a learning disability that required one. A foreign language is required for college admission, so basically no option but to buy a textbook. And the high school does not provide a portable device to access the online textbook either.
As far as the book goes, it is just your generic 2nd year high school Spanish text. The book has most of the expected material, with the typical cultural pictures and conversational topics. The online version is a little hard to follow, too much scrolling, etc. Just hard to absorb. I don't recommend the online version.
