@binbacteria one of the challenges I experienced here would be the road signs. I drive and I do try to go out station whenever I can and from that I have, in most times, ended up getting lost ^_^ which is both an adventure and misadventure. Now, I cannot go without a GPS.
Aside from road signs that are sometimes confusing to read, it was a bit of a challenge to like spicy, savoury food. Eventually, I began to like it and now I can't live without it!
@TatsukiAbe I agree that when doing postgrad studies, better go for the popular ones as well as countries that also offer employment for postgrad students. The UK has been strict lately (no more of the 2 year pass that allows fresh grads to find jobs).
