Yes, it is correct.
AnswerOne says "Jill and I" to be polite; this is not a grammar issue. (The speaker puts him-/her-self second.)
Whether one says "Sarah and you" or "you and Sarah" mightbe a grammar issue.
• One would put "you" or Sarah first if one wanted to emphasise it. For example, if "you" and Sarah had both worked on something, but "you" had done more work, it would be "you and Sarah".
• One would put "you" or Sarah second if one wanted to emphasise that one was correcting a mistake. For example, if "you" had said that "you" and Colin had caused some disaster, but the speaker wanted to emphasise that it was really some other thing, that "you" and Sarah had done together, that caused the problem, the speaker would say, "you and Sarah".
Otherwise, one would probably put "you" first to be polite to "you".
no it is not correct to say you are not for sure instead you can say in proper English that you are not sure about something
No. In English we say "How old are you?"
Yes.
No. You would say:'Suddenly'
More level.
Sarah and I Sarah and I is incorrect. You would not say "Meet with I" so you would not say "Meet with Sarah and I." It is grammatically correct to say "Meet with me." ... Soooo the correct answer is "Meet with Sarah and me." Hint: to figure out when to use I/me take away the other personor pronoun (like we did above) and see if the sentence is still grammatically correct, if so, that is the one you use!
it is not correct English, you rather say still
It is correct.
It would be more correct to say, someone who.
It is correct English to say decent skill but not decent ability

Sarah or Sara is correct.

Yes, it is correct to say out of compliance with. It means out of help with in English grammar.
The correct spelling is "Sarah" with an "h" at the end.
No, it is not proper English to say "on tomorrow." The correct phrase is "tomorrow."
