How many hours do you 'actually' study?

well ofcourse taking five minutes breaks.

I have a math exam tomorrow and i studied 5hrs for it ! That hard studying better pay off.

Also, a few days before, i studied 6hrs for a commerce exam ( 3 hrs for two days)

AND we have 11 exams all together, all in one week, two exams per day :S

I just wanted to know how many hours you ppl take to study?
