Expert writing Tips

Best practice

When using "within 3 months", ensure the context clearly defines the starting point from which the 3-month period is measured. This avoids ambiguity and ensures clarity for the reader.

Common error

Avoid using past perfect tense with "within 3 months" if the action is ongoing or has a future implication. For example, instead of "The project had been completed within 3 months", use "The project will be completed within 3 months" or "The project was completed within 3 months", depending on the context.
