Three questions separate these eight nouns: was it intended, did it arrive at once, and how far down the chain is it?
When something follows from something else, three things are worth knowing about it:
Was it intended? outcome ←→ side effect · byproduct
When did it arrive? impact ←→ repercussion
How far down? consequence ←→ knock-on effect
A Band 6 essay answers none of them, because result answers none of them. A Band 7 essay picks the noun that answers the one that matters.

Whatever happens, these findings have serious how cities are planned — a question of interpretation rather than of events.
The change had an enormous impact the daily routine of millions.
Name a direct, a delayed and an unintended consequence, and check each noun matches its type.
Policy: a city introduces free public transport for everyone under 25.
Use a different noun from this sprint in each — and make sure the noun matches the type you were asked for.
Three sentences. A different consequence noun in each.
If your noun does not signal 'unintended', the reader will not know it was.
