BK Tutoring (Chang)

Two separate reviewers specifically confirm Chang's Nat 5 Mandarin tutoring, with one student (who had studied Mandarin abroad but taken a 3-year break) crediting her with understanding the Nat 5 syllabus specifically after struggling to find anyone who taught to that level rather than just HSK; strong prelim results are cited, and Chang is praised for coming well-prepared to every lesson.
