yo im back...

since i am studying in NYU now, all of my notes language will be English...

maybe it will be a little bit inconvenient and difficult for me... but ...i think it's after all a good way of improving my writing skill in English...:)

I am struggling with the final, maybe have no time to update notes soon enough....however, in this coming winter break, i think it's a good time to re-write all the notes i have taken and post them online...
