I'll be immigrating to the US on the third week of January. I'm a 12th grader here and I was planning to do 12th grade there from September. It would be better if I could enroll into a school on February and take the remaining 11th grade classes. Are there schools that will allow that? I go to a very competitive school and our scores are seriously deflated. I'm barely in the top 25%. Will this be an issue for getting into a good school? I want to go to a competitive school with a lot of AP courses offered because I've already tackled AP level material here.
Also, what academic documents should I bring? Will a testimonial stating the difficulty be helpful?
I'll be going to Queens, NY.
