I started learning Japanese on my own and bought all the textbooks you can imagine. While you can learn grammar from those textbooks, listening and speaking skills require a lot of practice, preferably with a native speaker. Chika Sensei is approachable and attentive, she checks my daily assignment and make suggestions on how to improve my accent and pronunciation. Besides, she also asks follow-up questions relating to that same assignment so there is always more chance to practice. I highly recommend her course to anyone who wants to speak like a native.
