Expert writing Tips

Best practice

Vary your vocabulary by using synonyms like "finished", "concluded", or "accomplished" to add nuance and interest to your writing.

Common error

Don't use passive constructions like "the task was completed by me" when you can use the more direct and concise "i completed the task". Active voice makes your writing stronger and clearer.
