Study.

Exam season is coming so fast that I can't recognize these days are exam season. Because I worried about the record, I start to study. I didn't study these days, so it was hard to concentrate on teaching materials. But I had to study Prof, Lim's book, and make a drill book. I hadn't make it at all that I should do unfinished 33 days work. It is quite hard that 1 day work take about 1 hour. I'm now doing that work although time is already 1 am.
