  Common Errors

  • ❌ ~~By 2030, I will finish my degree.~~ → ✓ By 2030, I will have finished my degree. — "by + future time" is a strong signal for future perfect.
  • ❌ ~~This time tomorrow I will fly to Paris.~~ → ✓ …I will be flying to Paris. — "Action in progress at a future moment" uses will be + -ing; will fly merely states a decision.
  • ❌ ~~I will have finish it by Friday.~~ → ✓ I will have finished it. — Past participle follows will have.
  • ❌ ~~When you will arrive, I will have cooked dinner.~~ → ✓ When you arrive, I will have cooked dinner. — Time clauses still take simple present; no exceptions even with advanced main clauses.
