How many lessons in each Tree?
I often find myself looking up the number of lessons in an individual skill tree so that i can plan for how long i will need to complete a skill tree, or how many new lessons per day to finish the skill tree by a specific date. Is there a way to get the number of lessons in a skill tree without counting them. Like, a spot on the web or in the app that just tells you how many lessons there are total, and that updates when new lessons are added? If this doesn't exist already, is there a way i can get involved with trying to add a counting feature?
Each course varies in length. The German and Norwegian courses are the longest skill trees, while the shortest would be either Japanese (which is only available on iOS and Android) or High Valyrian. Here's a discussion displaying statistics for each Duolingo course:
