When I start to study Chinese in TMCC, i think they are quite serious and professional instead of other schools which ask you to buy several books. TMCC have 4 levels books to explain to you the chinese grammar, to give to you the minimum language for the daily life and to study or not the characters. They have also some tools to let you to improve your prononciation. After few lessons, my Sichuan accent has desappeared. Teachers of TMCC are high chinese level ; they give you tips to speak better than standard chinese spoken. I believe that TMCC teachers help me a lot for professional and daily life communication.
