I have a student who is taking an advanced Mandarin high school class. The standards are extremely high. Even though the student is smart and works extremely hard, she cannot meet the standards for tones, vocabulary, grammar, and writing style are very challenging. If you are experienced at teaching Mandarin, and think strategically and analytically about language improvement and getting great grades, please contact me! Let me know your experience and what you would charge to drive to Los Altos. Thank you!
