WOW...just came back from four and a half hours of physics tuition...I can't even believe myself that I just went through that long hours of tuition...of course only with the help of coffee I am able to stay alert and that causes me to be wide awake even now...and from my past experience that will lead to studying the whole night...and i will need another dose of caffeine to keep me awake through the day...sigh...the things I do to get an A for my exams...
