mugging?

i really need to study. but i just can't make myself do it. get down to some serious mugging, especially for the test tomorrow. especially for social studies. i'm planning to complete every single question from the maths/a maths ten year series book in preperation for the prelims/o's. planning.

why is studying called mugging anyway? the only 2 definitions of mug that i know of are cup, and to rob someone. so it's either 'cupping' or 'robbing'. i suppose robbing is a more suitable reason, since you kind of steal the knowlege from the book and put it in your brain.

the above paragraph shows the harmful effects of severe boredom caused to the human brain. therefore, it is advisable to avoid being in constant boredom in order to minimise chances of getting severe brain damage.
