5 Years in High School???

<p>Hey y'all. My problem is that I am a student from Ukraine attending an international school who isn't very informed. I've been planning on applying to a UWC school next year (I am currently a sophomore), but apparently this is impossible due to the fact that Ukraine only accepts applications from juniors. With my schedule for sophomore-junior years I will be able to obtain an AP diploma (if I pass the exams, which I hope I can do). Should I consider applying to UWC next year? Because if I get in, I would have to spend 5 years in high school in total. But then I would be able to obtain an AP and IB diploma (hopefully with good grades, had a 4.0 last year and hopefully a 3.9 this year). Should I consider applying to UWC? How do American colleges view 5 years of high school? Thanks in advance and sorry for the lack of clarity! </p>
