German as a foreign language, DaF who passed the exam and studies in German

Kristina is super smart and able to give professional advices. I got quite practical suggestion about speaking, grammar and the way to express, she is not only great for students but also very helpful for people like me, who hope to improve English in academic and daily life. Btw, she can also teach other things, like German, painting, etc., don't hesitate to give a try.
