Please help me!!!!!!!!

I am Swapn, I live in India and I want to study in a US high school.
I have a couple of questions.
I am, as of right now in limbo, like my 10th grade results are pending but I know I will get into 11th grade.I will nee Financial Aid too.
What I want to do, is repeat 11th grade in the U.S.
What I want to know is:
1)what kind of questions I mean what is the syllabus for SSAT?
2)How do I study for SSAT?
3)Are questions based on specific grades or just general levels?
4)If I am giving the test to repeat 11th grade do I get 10th grade level questions or 11th grade level?
In some posts I have read about hooks,like sports and all, I have a few questions related to them.
5)I have been doing boxing for nearly a year and my coach said I was gifted at and I am looking forward to some
competitions is this enough for a sport/athletics hook?
6)I have been drawing for a 4-5 years now some of my paintings are also in the school gallery and our school’s yearly
magazine is this good?
7)Does a bit of bodybuilding count as sports?
A few general questions:
8)How does me being an Indian effect my chances?
9)Does trying to repeat a year effect my chances?
10) What proportion of getting selected are each a)Grades and SSAT b)Recommendations c)My interview and essays?

That’s all for now, thank you if you answer.
