Common Mistakes
Wrong tense usage
Let time words guide your tense choice.
Why this happens
Wrong tense shifts time without reason — past events in present tense, or finished deadlines still in future will. Narratives need consistent anchors; arguments may use present for general claims and past for examples. Markers notice when every verb wobbles between was and is in one paragraph.
