Pretty good, but you need some. We basic improvements:
1 - Allow users to highlight problem words, to create their own lesson. Then all the words we have trouble remembering can be in one place, and we can study those.
2 - When teaching sentences, tell us what each word means. Dont just give us a full sentence and the translation. How does that help us learn the language?
