Yeah, I've decided to panic later as well. I'll leave it up to fate. I actually emailed my professor in the midst of my panic and I think some of my hysteria got through in the email and he replied (very reassuringly) that I can come to Japan first and then prepare. He thinks there is sufficient time. I still think he's overestimating my capability to recall stuff I've learned years ago but anyhoo.........
To ooilingfan,
Anytime, man. Anytime.
