"Kesho kutwa tutakuja"

Translation: We will come the day after tomorrow

[LesOConnel]

We will come the day after tomorrow should be correct.

[brjaga]

Yes it should, report it

[Klgregonis]

Inconsistency problem again, the first sentence in this lesson required the day after tomorrow to come first, this one won't allow it. Both are grammatical English, one, is just less common than the other.
