Usually elite boarding schools, acceptance in spring is not allowed. Even though I need to contact Wyoming seminary, this should be the case. Wyoming recently gains strong popularity among Chinese students. There is heavy competition among Chinese students. Wyoming has a great acceptance rate to top university as well; usually 10% graduating seniors are accepted to IVY or most selective universities. Their philosophy of guidance office is not just to send graduates to IVY, but the right schools that student will succeed. Wyoming does not like high school rank system. However, Wyoming can be easily one of best schools in east coast of USA.
First, you need to find which schools can accept you for January term. As I mentioned, not all schools will accept. Also, it is the season for the fall 2013, and it means that you are somewhat late for the spring application, and rather time to prepare for the fall.
Nevertheless, we can do some research for you and for your long term academic plan. Going to a high school is not an ultimate goal. You might want to discuss more about your future. if you want to go one of top universities in USA, certainly we can work together. Please contact us and make an appointment.
