Getting tested on words I have not been taught yet!
When I finish a "Spanish Skill" such as "V. Past" and then do "Lesson practice", I get new words from the next skill (in this case "V. Pres. 3") that I have not learned yet!
Once I do start taking the lessons, then "Lesson practice" seems to keep testing me on only the same certain few old words over and over again and ignore other old words!
I have a similar problem - I often "complete" a lesson but don't end up being taught or tested on all the words in a lesson. I only know this from using the mobile version, where you can view the words you are going to learn in each lesson (versus just a sample list of the overall skill that you see on the web version). Will these words then pop up later future so I can learn them, or will they forever be stuck in the lesson where they are supposed to be taught, so that I have to redo the lesson and hope I get that word?
