3Blue1Brown - A great Youtube channel from a guy that explains math in a very visual and intuitive way. It's not like one of those descomplica lectures, he's more focused on explaining the intuition of things, but you should definitely check him out.
Mathgurl - A good channel in Portuguese. She makes short videos talking about math, and they're good for chilling and getting more comfortable and sympathetic towards math.
Khan Academy - Great auxiliary material for physics and math.
Library Genesis - You can find any pdfs you want there.
Physics Volume 1 by Randall Knight - It's a university-level textbook for Classical Mechanics, but it's pretty much the same kind of mechanics you'll see in Fuvest. I recommend it because it's my favourite physics textbook, and it offers much better explanations than regular high school and vestibular textbooks.
I think that's it, but don't hesitate in asking more questions if you want.
>>11692483Naval Engineering. I didn't use much physical material (I'd just download pdfs), but I still have some of my high school textbooks, although I left some in the locker and never came back to pick them up. You can have them, btw, if that's why you're asking. Although I don't think they're particularly great compared to any other hs textbooks.
