Redo senior year or go to college?

I finished my senior year of hs in a foreign country and im moving to the US in a few weeks. Im wondering if i should redo my senior year in the US so i can get used to the American school system before jumping into college. Im fluent in english but everything i learned in school from 3rd to 12th grade was in arabic. Also, will i have any problems in history class? I obviously never studied American history before.
