Expert writing Tips

Best practice

Use "had completed" to clearly indicate that an action was finished before another point in the past. This helps establish a sequence of events and avoids ambiguity in your writing.

Common error

Avoid using "had completed" when a simple past tense is sufficient. Overusing the past perfect can make your writing sound unnatural. For example, instead of "I had completed the report yesterday", use "I completed the report yesterday".
