There are a lot of difficult parts about learning languages. One that has not been addressed in any of the methods I've tried is understanding. I just returned home from a trip to Europe and spent quite a bit of time learning a couple of the languages. But even when people spoke to me with words I knew, it still took a while for me to process the word and translate it -- sometimes even with really simple things that I should have known better.
How about an option for an audio quiz? Play the audio first without the written word and have us choose -- or better yet, type, so it's not obvious in the multiple choice -- the translation.
I'm just trying to figure out a way to understand the language better when it's spoken to me the next time I go.
