"Por que você não vem com conosco?"

[bmmartins]

If you use the word "conosco" you do not need "com".
The expression "com conosco" is wrong.

[Rennvotur]

Exactly.

Is the given answer right?? Looks like como is surplus to requirements here....

[erudis]

It's wrong. Either you say "com a gente" or "conosco / connosco".

[Quentinho]

Thanks Erudis. I'm starting to get bored of Duolingo. There are just so many mistakes in those more advance lessons, and I can see that 2 months later the corrections haven't been made...

I've found that reporting the problem usually fixes it I've had many e-mails from duolingo explaining my sentence is now accepted, or the problem has been fixed. Duolingo relies heavily on user feedback.

[Rennvotur]

Yeah, the thing is that they hire ONE native speaker for each language and think that that will be sufficient enough to do all of the lessons and then over time they improve it. Which is fine, except that it makes everything really slow and that gets backed up really quickly. They also do not even CONSIDER non-native speakers who speak fluently. But yeah, even after reporting the problem, I have come back several months later (6-9 months) and the problem has still not been fixed, especially with audio.

[Rennvotur]

^ Yep. Take it from the native speaker. :)

This is pathetic that this comment is four months old and this is still not fixed I'm getting tired of all the errors in this site too.

Até o momento nenhuma providência foi tomada em relação à palavra "com", que sobra na frase em Português.

Cientificado de novo o Duolingo, n/m/d.
