<p>aliah, day schools are private schools. You can ask your 7th grade counselor for help to get into one. They’re expensive but if you score very high on the entrance exam (both math and English) they’ll probably offer you a scholarship to make it affordable.
Explain to your parents that public schools are not nationally subsidized in the US and have no national program/curriculum; they receive a portion of their budget from the local taxes: Of course, the higher the taxes, the more money for the school. There is, of course, a compensating mechanism, but depending on your state it can be very inadequate and in any case there is no law like “give more to those who have less” (i.e., there isn’t a lower-income school that receives more money than a higher-income school). (I won’t go into details like Title I etc but these don"'t make a school in an impoverished area “rich”.) In addition, parents are meant to participate in the process, including with money and PTA. There is a school board where some parents sit. Schools may have different sets of required classes, different textbooks, etc. In some schools, it’s possible to start Algebra in 7th grade, in others it’s only possible in 9th grade. Consequently, some students will be 2 years behind in math compared to the others. It’s especially noticeable in the math sequence: For example, some students finish high school with precalculus (that’s the norm) whereas in some schools students BEGIN high school with precalculus. UCBAlumnus is someone who knows the math curriculum so if you’re good at math seek him/her out on this forum and ask how you can get into a sequence that is as accelerated as possible. You’ll have to determine what type of math you’re comfortable with. Have you done geometry proofs for example? Have you started working with x2+y2?
What level math are you?
If you’re starting Geometry or Trigonometry or higher, you may be admitted to a community college. There ARE 12 or 13 year olds who are gifted enough for that and the US is very flexible about it.
BTW, for someone who’s been in the country for only a few months, your English is excellent, and I wish all 6th graders, who had the benefits of being immersed in the language for 10 years, could write that well. Even though there are mistakes, they’re likely remnants from your native language. A counterintuitive way for you to improve your English is to keep your native language up by reading, writing and speaking it, since your progress in English will depend on your abilities in your native language. Students who “drop” one often meet a “wall” in their progress. For English, even watching TV, going to the movies, and reading kid books will help 
so have fun.
Finally, in the US you’ll be looked at in comparison to your grade, not your age, so when you get to college this will actually work to your favor. But you have to stay strong till then. :)</p>
<p>Look into CTY, but you’ll have to qualify.
