Under Ariel's guidance, Anna (my 12-year-old daughter) has undergone a remarkable transformation in her Mandarin proficiency. Her evolution in this complex language is evident in the significant progress she has made in forming sentences and improv vocabulary. I specifically appreciate Ariel's commitment to addressing specific challenges with Anna, such as some of the words that she cannot quite comprehend, she has been incorporating interactive exercises to help her memorize. This approach aims to reinforce Anna's practical comprehension and ensures her understanding beyond a surface acknowledgement.
