I'm so tired today. don't know why. wake up late in the morning but I managed to go to breakfast early as usual. then, our campus was blackout, and tell you, it was so hot, until my body sweat like hell. after two and a hour, our campus in turn back to normal. so, most of our classmate went to the library.
it's hard to study for me because I don't have any book to use as a reference. lucky me, the wi-fi is so sporting, and I can search for the information easily. and most of the notes can be found there. still a lot of things to study and to refresh, I just hope I can through this weeks before the exam start next week.
