I have been taking lessons with Kerstin for over a month now and have only great things to say! She is very organised and always has tasks prepared, as well as homework where necessary. As I'm preparing for the TestDaF, her support has been invaluable. She gives detailed, constructive feedback on my essays and offers practical advice for the other sections of the exam, meaning I always know what to focus on next. If you're looking for a structured, supportive teacher, I wholeheartedly recommend Kerstin!
