What do you trust more the school textbook or Duolingo
HEY, ALL, So I was looking at duolingo and my textbook happened to be out. and it said something was wrong that said was right in the textbook. Whats the most trustworthy resource?
Why don't you give a concrete in-depth (concrete) example what is different?
Have you already checked the sentence discussion? Have you asked the question there to discuss with advanced French / native French users and course contributors???
If your text book is correct on that single "word / sentence / explanation" and you get a positive feeback from the "sentence discussion", the DuoLingo database might just miss the correct alternative solution and you manually would have to report it.
This is not DuoLingo French related (English is enough):
Have you really never run over the "report" function, where the sentence course database is just missing many alternative correct / valid answers?
