I strongly disagree with some opinion that Portuguese is not a difficult language because it is even for natives. For you to study in here is necessary acknowledgement in our language depending upon what you wish to do. If you intend going to some university, our courses are developed under Portuguese language; if you intend to enter high school I believe there are schools that provide it in another language (you can make a research in order to confirm this); and if you desire attending a Portuguese course, you should come with a basic comprehension of the idiom. Good luck.
