Hey there! I thought it might be useful to create a list of the sentences taught in the Latin course. Hope you find it helpful! So here's a full (at least all that I encountered) list for the first skill!

I've also added all the words taught to the Duolingo wiki. Feel free to take a look at that as well as I've done the words for Intro: https://duolingo.fandom.com/wiki/Latin_Skill:Intro
