Hi Kiki,

Where did you read or see the following sentences?
"I have got headache."
"I know but i am doubt."
"I want geting the exactly answer."

I'm asking because none of those sentences are correct. Please try to use only sentences you have seen or read somewhere before. If you don't know if a particular sentence or phrase is correct you can ask.

For example, the phrase "i am doubt" does not exist. You invented that phrase yourself. How can you be sure that all the phrases you invent are correct English?

Thanks,
Torsten
