- Future perfect: will + have + past participle (completed by future time)
- Progressive forms show ongoing actions; only use with dynamic verbs

- Future perfect progressive: ongoing action with duration at future point
- Never use progressive forms with stative verbs (be, seem, know, love)
Last minute tips
- If you see specific time (yesterday, last week), use simple past, NOT present perfect
- When choosing between perfect and progressive, ask: Does it emphasize completion or ongoing duration?
- For past perfect, look for two past actions - the earlier one gets past perfect
- Remember: Regular verbs add -ed for past participle; irregular verbs have unique forms
- In exam questions, time expressions are your biggest clue for choosing the right tense
