I have some confusionam a bit confused about using past perfect tense.
Are both of these sentences correct, or is only the past simple tense correct?
Sara went to bed as soon as she had (she'd) finished homework.
Sara went to bed as soon as she finished homework.
Do both of these sentences mean the same thing?
Everyone had gone home when Sarah got to the party.
Everyone had gone home when Sara had got to the party.
If the sentence was rephrased as
Everyone went home when Sara had got to the party.
does it mean the same thing? Which event will be 1st action and which will be the later or 2nd action?
What happens if I use both "when" and "before" before past perfect sentence while the mostly used before past simple sentence?
Would you give some examples and explain them please?
