To learn Korean quickly, a short, repetitive, and playful learning program is helpful, and Wink is highly recommended. It uses various methods to stimulate interest and helps children learn the principles of the Korean language through repetition. Both physical workbooks for hands-on writing and audio-visual learning are provided, making learning effective. For children preparing for elementary school, an 'intensive Korean course' is also available, which can help them master writing within a short period (e.g., about three months).
