How to assign certain topics?
I have French II, III, IV students signed up. I don't want them to go through all the beginner lessons. How can I assign only certain lessons?
I don't think you can, as an Educator, "unlock" a skill for your students. They need to have unlocked the ones before (at least it's how it works in the main website and your student are, at the end, using that I believe).
But if they already know the basic, they can just take the placement test when logging in to start further down in the tree (depending on the result of the test).
It could be a good way to detect the students that have some difficulties with basics too.
