In A-school and Power school, it is set to about 8-9 hours depending on the day, the rest is performance based (GPA), M-F. In prototype it is more of the same, performance based extra hours, with set hours being shift work 0830-1630, 1630-0030, 0030-0830, in addition, you dont exactly get a set schedule as far as weekends are concerned. Any other questions, I am pretty fresh out of school, willing to answer.
