Take precalculus regular during the school year (you do NOT want compressed summer format for it) and make sure your GC indicates you have Dyscalculia and have taken that math regimen in spite of it. If you manage to get an A in Physics, too, it’d also show ability and good faith effort. It should be OKeven without calc.
Have you taken APUSH? AP Gov (US+Comp)?
I assume you plan on double majoring in foreign language and international relations + foreign language minor?
Odds are, you won’t get into any Ivy+ school. Odds are good for no one. 
So your first job will be to find colleges with high-level foreign language courses + year long study abroad AND about 30-40% acceptance rate.
BUT your singular dedication and gift in Foreign Languages would be a big plus for Oxford or Cambridge, St Andrews, Durham, Aberdeen, Exeter, SOAS… if you can afford college in the UK.
In addition, keep Middlebury and Dickinson on your list. USC (Columbia) Honors has an extensive application but is very good for foreign language. Finally, look into Critical Language Flagships.
