Sandra is one of the best teachers I have ever had.
She is very knowledgeable and professional in her job. All the materials I received before and after classes were not only thoroughly prepared and contained a lot of useful information but were also tailored to my needs.
Sandra is a very friendly person and easy to talk to, thanks to her good-natured character. She shows great engagement in the learning process and encourages you to become better at German at every step of the way.
She helped me prepare for the speaking part of the Goethe C1 Exam, which I passed without any problems.
