It would be very useful for the chinese course, if when you hover over a word the pinyin pronunciation would pop up with the hanzi. I often remember the characters, but forget the pronunciation when I'm typing.
I can very much tell the poeple here making this course where chinese speackers themselves. Does not always make sense. Like for one I put in, "How should we get to the hospital?", and the correct answer was, "What transportation can we get to the hospital?". I think it can be worked on very much. :/
