Leif is a very experienced, knowledgeable and encouraging tutor. He has helped our 17-year-old daughter on her A-level History. Leif is professional and quickly identified the gap where my daughter needed help. My daughter has not only acquired the subject knowledge and skills but also been motivated to be passionate about the subject. After a few lessons with Leif, my daughter started to invite her classmates to form a group of study buddies. They worked hard and revised seriously for school tests or exams. I am so glad about my daughter's progress and would like to express my sincere gratitude to Leif's dedication and professionalism.
