Its Exam Time Again!

Assessment-1 starts coming Monday in my college. And the first paper is our worst: Propulsion. Yesterday night(around 11) my friend AR texted me and the chat went like this(my shortest SMS chat, i suppose):

AR: wat doin? studyin still?
Me: ya.. you?
AR: am goin to sleep. do u understand?
Me: I understand that u r feeelin sleepy. s tat sentence such hard to understand?
AR: i asked if u can understand wat u r readin. gud nite.
Me(confused and irritated): No. good night.

Reading  textbooks  always leads to confusion and mental tiredness. :-) Really. The great Bertrand Russel said this:

Men are born ignorant, not stupid; they are made stupid by education.
