Hallo! I will be applying to university in Germany in the next year, and will need to learn German as soon as possible. I have a very basic sense of the language, but am a very fast learner and will make you a proud teacher! In exchange, I can offer you excellent English or Portuguese lessons (I work professionally as a teacher, so you will not be disappointed!)
Please let me know what you think, or if you know of anyone who may be able to help me. I will be happy to hear from you.
