Am I eligible to study abroad?

I live in the US. I have always wanted to study for a year at a school in England. I'm a sophomore. Anyway, I have always had great grades until this year. I have done online school for two years. The first year my lowest grade was a B, but I had mostly A's and A+'s. However, this year I kind of washed up a little and failed a couple classes. I took standardized tests last fall for my state and scored above the 95th percentile, if that happens to redeem me at all. Is it now unlikely for me to be accepted into an abroad study program, even if I get my grades up next year? Thanks
