Thanks a lot, snowcapk! Glad to hear that. I don't know how much a sub score can mean for the app, but I guess a good score won't hurt. Thanks again for your information!
I just checked out online for registration of the sub test. It turned out that the registration has already been closed. Sad... I'm not really sure whether there still will be sub tests available this year. So if anyone has not registered for the general one yet, go do it NOW. Does anybody know that whether there will be any more sub test this year? Thanks!
