i dont believe the hints given. total crap! i'm STILL doing my tutorials eg tutorials, simple beam experiment, i cant believe that experiments can be done online! total crap! physics tutorials..arg. i totally believe the whole world around me is already revising there stuff! so when you see me in school pls dont ask me this qn:"how's ur revision going on?" i'll just walk off...BAH! the whole sch's atmosphere is super intense now,you can totally feel the mugging spirit! it's so spiritual lah! unbelieveable...everyone's so into the mood. I NEED A LIFE! i dont anymore energy to resolve forces. there's no more area for me to move. my body is aint efficient, input doesnt equals to output. my body's temperature is rising, pressure is increasing. the stress is causing strain on my body and i'll soon fracture. all the terminology and formulas...sian
