"I highly recommend Krzysztof as a math tutor. He supported my 17-year-old son in preparing for his engineering college exams with exceptional dedication and expertise. Krzysztof was highly organised, using a clear and structured approach to each lesson. He managed to encourage and motivate my son throughout their sessions. His explanations were clear, and he provided thorough instructions, along with additional materials for independent study between lessons. Krzysztof also supplied previous exam papers, which were invaluable. Although the results are not yet released, I am confident that his efforts and techniques have had a very positive impact on my son's performance."
