Thats soo cool! Nice to know somebody else like this.
I have a very similar situation to yours, and understand what the struggle is.
I came to the United States from Israel in 2013, and decided to take APUSH my sophomore year of highschool as well. I have been doing okay in the class, but my biggest problem is the prompt based questions. My teacher has been telling me that since English is my third language, that I misunderstand because of my language barrier, but that’s not it. I have been looking for more practice questions online, but there are simply not enough of them!
