"Be Going To" for future plans and arrangements
Rewrite these sentences using "be going to + verb". Use contractions ("he's" not "he is") where possible.
All of these sentences are written in the present continuous. But the present continuous is only used for arrangements (you have decided where, when, who with ...). We use 'going to' for general plans. If you think the sentence is correct, tick 'correct', and if you think it should use 'going to' tick 'wrong'.
