I was a mentor in high school and also in my gap year in Poland, I loved to teach portuguese to kids of the primary school and I learned a lot with that. I am willing to share my knowledge of portuguese language and help you achieve the level you desire. I like to teach in an interactive way and I can also show you a little bit of brazilian culture, music, history and whatever you are curious. We can meet once a week or twice in a cafe or wherever you want to. Also, I can teach english to kids as I love to do that.
If you are interested, let me know.
I can also help you with TOEFL or matura. I speak polish (B1) and it can make things easier.
