Grrrr... Why are most of the light bulbs missing from most of the French tree?!?
Why why why would duolingo provide great little mini-tutorials for, say, about the first one-third of the total number of skills, clickable on a little light bulb, AND NOT CONSISTENTLY PUT THEM ON ALL THE REST? This is beyond frustrating. This inconvenience is huge and makes zero sense. In addition, it appears the French trees can arbitrarily change with no advance notice, and to the detriment of the student's prior progress. I was excited about using duolingo extensively this fall, but on further reflection, I don't think I'm going to subject my students to such frustration.
