Your answer has the wrong words, your answer translated says that Biology and Chemistry cases you the hardest, is that what you wanted as your answer?
2. Welche Fremdsprachen außer Deutsch möchten Sie noch lernen? Warum?
Your answer seems to have the right words just they seem to be a little out of order, your answer says, I would like to still out of german spanish, english and russian learning, because these foreign languages most I like, is that what you wanted to say?
