Hello. My name is Raj Patel and I live in the UK. I want to go to medical University in China but I have to learn mandarin in 4 years. How hard is it to learn mandarin and is there a realistic chance that I can actually talk and write mandarin with 4 years because I don’t want to go there if I know its going to be very difficult to learn. How many hours would I have to put it to learn mandarin?
