So I am an American student who will be entering college in the fall. I speak English and Portuguese at home, and I'd like to study Portuguese. Because I only speak it, I have no grammatical knowledge of the language, however, I do know a bit of vocabulary. I'm wondering if I should bother with a placement test, or if I should just start with the beginner's course to develop a solid foundation.
Also, my school only offers Brazilian Portuguese and I speak European Portuguese at home - I worry that if I don't study it now, then I may never do it. I have heard that the primary difference is in pronunciation and because I already pronounce Portuguese words in a particular way, then that will carry over to the new words that I learn. Will the differences be detrimental to my speaking?
