I like the Play it exercises very much but wish they were much longer.
I wish there was an option for turning off the difficulty buttons that you have to select after each question in the exercises - they really slow everything down and I don't find them particularly useful.
Far too many of the answers for the multiple choice quizzes are one of the first two options!
The entire interface, navigation, the different sections, Tools etc on my laptop is outstandingly good. I can't see how this can be improved so please don't start fiddling with it in the future in the name of upgrades or progress unless there is a seriously good reason for doing so!
I have had the German course now for a couple of months and am overall really impressed and enjoying learning German. I'd really like to practice speaking more and am planning to go to Germany later in the year.
