Expert writing Tips

Best practice

Use "when I realised" to clearly indicate a specific point in time when understanding or awareness occurred. This helps to create a timeline or sequence of events in your narrative.

Common error

Ensure that the context clearly establishes which event happened first. Avoid using "when I realised" if it creates ambiguity about whether the realization preceded or followed another action. Consider using past perfect to clarify the sequence: "I had already started the project when I realised it was due the next day."
