It is definitely ok for you to reapply for the same school，could you please tell me which grade you are and which grade you are applying to so that I could give you the appropriate advice.

which school you take classes right now?

Well, if you're planning to apply to the same schooll next year, you may. However, I would advice that you do thorough research to get to know what they are looking for and rationally assess if you truly fit the profile of their student.

There are many excellent schools. I wouldn't be too focused on any particular one given the competitive nature of today's top schools. I would advise that you diversify you choices.

If you need a school with boarding facilities near New York city for fall of 2017, feel free to contact me.

yes, it always happen and be well encouraged to apply again. For future success, it is better to provide evidence of improvement as a return applicant and work with your consultant and parents to apply seriously. Good luck!
