New words in a lesson with no definitions
I just started Verbs: Present 2 in my German tree. The first activity of the first 'lesson' was to translate a sentence, without any definitions for any of the words.
I think the sentence was "Ich weiß, wessen Sohn Sie sind." Technically, I have learned all of those words. However, up until now, my only definition of 'weiß' was white, which obviously doesn't make sense here.
I'm studying on my iPad, so I can't report the problem, so I thought I'd put it here. This is a big problem in my mind - you need to give someone a chance to learn something before testing them and discouraging them because they have no way of knowing the correct answer!
