Today (Sunday, in my feeling), I slept a lot. In addition, I don't have any class on Monday morning.
That's why I'm getting up this late (4:00 am) and doing PHYS's assignment. I really got a strong concentration for study in these days. A year ago, I could never study like this. But even I spend that much time on study, my grade would not be A+. ...Oh well, this is normal for most of the non-native English speakers (especially whose first language is totally different from English), so I'll keep this pace.
