Every student’s learning rate is different cause it depends upon many different factors, like how many class attended every month and of course every student has his own aptitude toward foreign language learning.
Based on our experience with our standard course of 20 classes per week, a student can reach a survival Chinese level in more or less 2 weeks; with this level the student can hang around Beijing and have simple daily communication in Chinese (self introduction, ordering food, asking directions, shopping, expressing simple topics related to daily life, etc).
