Common mistakes to watch for
Mistake 1: Choosing by sound only
Words like their, there, and they’re sound alike, but the spelling depends on meaning.

Ask whether the sentence needs a noun, verb, adjective, adverb, contraction, or object form.
Mistake 3: Mixing spelling styles
For a US audience, use American spelling consistently. For a UK audience, use British spelling consistently.
Mistake 4: Using old-fashioned business phrases too often
Phrases like Please find attached are not wrong, but simpler alternatives often sound clearer.

The real value of a practice test comes from reviewing the questions you missed.
