I had written, to include "my" for "we": My učíme je psát. It was marked as incorrect with the correct version being: "Učíme je psát."
When you include "my" the most common correct word order is "My je učíme psát".
is 'my ucime je psat' wrong ?
I think "je" is one of those pronouns and other words that need to be in second place (that is, after the first unit of meaning) in the sentence or clause.
It is not wrong to include "my".
And we accept several version of sentences with 'my'. To evaluate your answer we need to see the entire sentence though.
