Convince my parents to let me go to boarding school.?

-I am 14 years old and although i do like my hometown and friends, i would like to go to boarding school for sophtmore junior and senior years of high school (its too late for freshan) im an excellent student straight A's honors classes and i would like to be challanged more. I have narrowed it down to a few schools with good financial aid programs and now i need to convince my parents. They are usually very supportive, but ive brought this up before and they dont really seem to keen on it. They dont realize that there are all types of baording schools not just "troubled teens" ones. How can i convince them to let me apply?First of all tell them it's what you want and you think it would be good for you. Then tell them that you've found a few schools with financial aid so it won't be too expensive for them. After that, tell them that not all boarding school are for troubled teens. Actually a lot of them are for more well-educated kids such as yourself. List off good reasons for letting you go. Don't beg though! Try to use the bandwagon approach... tell them that there are lots of kids going to boarding schools these days and it's a very structural learning environment. Don't forget to tell them you want to be more challenged at school and you think going to board school would be the best way to do that. Good luck.(:
