@caenlim While I can't give exact numbers (I'd have to rewatch and reread all of it again and constantly compare), there's very little that wasn't covered by the anime. And the least chapter that was adapted is 43 (the anime adaptation itself was announced in volume 3, so it mostly covers everything up to that and a bit of volume 4, albeit not in the same order).
If you want to skip what was covered in the anime, you might just as well skip everything until chapter 44 and begin from there. But of course, there isn't much there yet.
But it's great that there are even so many chapters available now, considering that there were only 13 until fairly recently. That Yuru Scans managed to put out so many updates over only 3 months, and is still going strong, is pretty amazing.
