Learning portuguese

I would think you would be able to find more English/Portuguese speaking people in SP. Try to find those and they can help
I too have 1 on 1 and professora pushes me more to going out and about and just try to practice.
I live in a much smaller city but try my best during a doctor visit, going to eat and shopping to practice. Not everyone can speak English but many try and I always thank them and  go back when I can.
I find the locals appreciate me trying and they are helpful.

i just started learning portuguese 2.5 months ago, but i'm roughly following this guide:

although, really, you should try to take advantage of anyone who wants to learn english.  you can set up a language exchange where you speak in english for 30 minutes, and then you speak in portuguese for 30 minutes.  i did this once with someone over skype.

there's an app called hellotalk, but i haven't tried it yet.  that might help

readlang and lingq will help you read portuguese stuff.

readlang is free.  i haven't tried lingq.com, but you do have to pay for it.
