Problem with vous and tu
When the question refers to sentences using vous and tu, it marks them wrong even when they are right. This happens when changing the English word you into French.
Your explanation is not clear enough. Without an example, there is no way we can know what you are talking about. Also, the French course is almost flawless, so you are most likely mistaken when you say, 'it marks them wrong even when they are right'. We would need more details to confirm there is a problem in the course, or to tell you why you are mistaken, and you would learn from that.
I say that because for now it sounds like many posts claiming 'I typed a right answer and it told me it was wrong'. How can we help you if we do not know more than that?
Here is an example of what I mean
It is like a multi choice question. I ticked the sentence: vous mangez comme un cochon.
The following message came up: You missed one of the correct translations.
Correct solutions Vous mangez comme un cochon Tu manges comme un cochon
My answer is marked wrong. This seems to happen whenever there are two correct answers. Help!
