Dr. Liu is very passionate teacher who makes Physics fun and easy to learn. His teaching uses a holistic approach that goes beyond just solving problems; he always emphasizes the importance of understanding the basic concepts and explains the connection between them. With his deep knowledge in Physics, Dr. Liu just knows how to get to a student's problems and fix them! Dr. Liu is not just sharp with the subject matter, he is also very patient and nice! Physics used to be a challenging subject for my daughter, but she now finds Physics interesting! Her grades improve dramatically since taking lessons with Dr. Liu and she gains a lot of confidence with the subjective matter!
