What's the difference between the "strengthen skills" button at the right side of my home page and each individual one within a lesson.
How does the one on the right of my screen know what level to test me at? I've noticed it seems to stick to the basics although I'm further down my tree?
I believe the difference is that the strengthen skills buttons (on your home page) tries to generally strengthen all you skills, and given that you haven't done basics in a while, (or at least that's what I'm presuming) it would focus a bit on those. However, strengthening individual lessons ONLY focuses on strengthening the words in those lessons, not on any others. Hope this helped!
Have fun learning Vietnamese!
The Strengthen Skills button on the home page works on skills that are not gilded. As you strengthen with this, you work your way farther down the lessons from basic to more advanced, gilding as you go, often strengthening more than one lesson at a time. (It can be a little more random than that, but that's the basic way it works.) The Strengthen button withing the skill focuses solely on that lesson even if it's already gold. This allows you to focus where you need to, OR choose to work in a more general way. :)
