best 3 weeks - 1 month program

[mat1979]

hi you knowledgeable people!

i work in europe

have a lot of holidays

is easier for me to go to china twice for 2 weeks rather than once for one month

wanna improve my chinese, which is rather poor, and i need to be in immersed/intensive program rather than a little by little program otherwise the lazy bitch that i am doesn't study enough.

for you, what would be the best choice for a 3 weeks / one month mandarin course in beijing ?

would it be better to do two 2 weeks courses rather than one 1 month ?

thanks for reading this
