Private 1:1 offline classes at Thats Mandarin

I booked 1:1 classes at Thats Mandarin to learn for my HSK4 Exam. Before I started I was asked what my learning goals are and the lessons were prepared accordingly. The software that Thats Mandarin uses has some minor bugs but it is a very good tool to review and to practise. I don't need to buy books or workbooks, everything is provied online. The teachers are very good and patient. They know how to teach foreigners chinese. I really like the classes there and my Chinese is improving quite fast.
