I teach people who don't have any background in Mandarin and those who forgot about their Mandarin Language. I provide lessons, exercises, and quizzes as well. I teach at a low pace to those people who are not familiar with the Mandarin Language, but it will depend on how you will catch up. I teach Beginners, intermediate, and advance Mandarin. That includes vocabulary, conversation, and making your own sentence in Chinese. I provide pdf lectures notes and books to my student for better learning.
It will be easy when you are consistent in learning Mandarin as your 2nd language and if you will use it in your everyday conversation with people.
It depends on the person's limit of eagerness to learn. Mandarin/Chinese language is a consistent learning language. It is not only in a matter of 6 months, but it is an everyday learning kind of language.
