Okay so here's my scenario:
I'm 14 (I'll be fifteen come December) and I'm from Denmark.
The Danish school school system has an offer that allows me to take a year in High School in USA, England, France, Canada, New Zealand, Australia or Ireland. The only requirement is that I have the equivalent of a C in all my core subjects and that I am 15-19 years old.
So, I'm thinking of finishing this school year (come June next year), and then having a year in a High School in USA. By then, I'll be 15, as already mentioned, and I don't think getting a C is very hard for me.
Info about the offer: I'm offered a 14 day preparation course in the country I choose, before starting in school and I will be living with a host family that has gone through 'training' to be nice to me. I can also sign up for 'Discovery tours', where I'm taken on tours with other exchange students to see awesome landmarks and that kinda stuff.
In England, Australia, France, Canada and the states, I can also choose which part I want to be sent to.
So to all you Americans: should I do it? Is High School an awesome experience, or does it suck?
Advise of all kinds is welcome. Also if you hail from one of the other available countries, feel free to give me some reasons as to why I'm better off going there. I will be listening
EDIT: I speak fluent English. My English stepfather of 11 years has taught me the language since I was 4-5 years old. I don't have self-esteem issues and I'm open to new people.
MEGA EDIT!: I'm beginning to lean more towards Australia.
