How do you challenge a level? This new format sucks, each lesson is way to short... with too much repitition, especially at the lower levels...
I also dislike to new format. It forced me to go all the way back to the beginning and the first exercise now has 5 levels and some levels have 25 quizzes which ask for the same words over and over again. Too redundant. I feel like I am working just to get through the levels instead of working to learn.
