Marjor in International Relations?

Hi! I have always loved global studies and politics etc. I am a senior and I had a weighted 99 gpa prior to junior year (hopefully it went up). I have taken 4 aps (us history, European history and global history which I got a 5 on all of those and ap Lang which I got a 4) and I plan on taking 4 more senior year. My SAT is not that good but it’s honestly because I haven’t properly studied for it, I plan on taking it again in October and subject tests in November. I want to apply to a competitive college because IR is a competitive major any ideas on what I should apply to? Also I want to drop Ap Italian because that class is completely useless and I’ve learned nothing, is it ok to drop my language ? Also I’m president of my school Model UN, captain of twirling as well as editor in Chief of yearbook. I just can’t seem to get my SAT in line ugh! Any advice ?
