Words Missing from Lesson
I'm noticing that some words that appear on a skill's lessons page will not come up in the actual lessons. It's usually just one word skipped, but often I won't even know it's been skipped until it appears out of the blue much later as if I learned it when I hadn't. That or I have to go back and check if the lesson covered all the words listed.
Anyone else? Can Duolingo fix this? It's really harmful to the learning process.
For each word taught, Duolingo generally has 3 sentences. Each skill is broken up into a few lessons with each teaching a few words. In a lesson, one usually gets 17 questions. It's possible, sometimes, one or more of the words taught in the lesson don't come up during a regular lesson. Redoing a lesson a few times generally helps get exposure to all words/sentences that it was meant to teach.
Though a few times I have noticed a word not come up after several repetitions but show up during strengthening.
