This tbh, I haven't learned any English for like 10 years probably, I started to watch English YT content a few years ago and it def helped me a lot, watching movies or anime or whatever and looking up stuff you don't know might be a great help, and as @The Wife mentioned I can recommend Babble personally too, if you want to save money just buy it with a Brazil VPN cuz they have the cheapest price there AFAIK
