I work in a global consultancy firm, and I took up mandarin out of interest. It's been three months, and I have thoroughly enjoyed classes! Mandarin is known to be one of the toughest languages, but learning here, has made it super easy and fun! It is a highly interactive class, that makes you work towards it and even with work and other obligations I find myself taking time out to learn and use it!
Something unique that I experience in the class is how the language is not taught from just a classroom perspective, but the teacher makes it a point that we learn the language for using it outside the classroom.
I recommend this for anyone who has even the slightest desire to engage oneself in another culture.
