Fluent is a very broad term and there is no actual definition to define fluency but there's absolutely no doubt when can get your level ahead, fast. After 18 weeks of studying with LTL (one Semester), we can generally get students to HSK3 level. Sometimes, with a lot more hard work and effort outside of the classroom HSK4. After two semesters we've had student hit HSK5 level which is a very solid level of Chinese. For more about HSK levels and definition, visit our HSK page.
