i didn't realize the duolingo web version explained the grammar so i always used the app... :/ how does that even work? if i go back to review old lessons will it still teach me the grammar i missed?
You just click on the skill, even if you already completed it, and the tips and explanations will show up if you scroll down from the lessons. Each skill, even vocabulary only ones, has grammar explanations and it is pretty neat in that it even explains how you use certain words not taught for different things. Also, check out the discussion tab for topics you still don’t understand.
