Question

Thank you very much.
Is it wrong to say "go out of the school?"
I also wanted to know if the following list is correct.

Joseph Conrad's Heart of Darkness (abridged edition)
The historical context of the novel, the narrative technique, the themes of colonialism and symbolism

Answer 1

You can say that, but it's not smooth. To leave the school or to exit the school -- both are smoother (and take fewer words!).

The list is fine if you add a comma after "colonialism."
