My father always called the school to get me out of class for a day of hunting, the next year after it started the secretaries would non-chalantly ask if I was hunting and then continue to tell him to tell me "good luck"... I made it through high school, 4 years of college and Army service.

IMHO, skipping school in high school prepares students for college more than high school itself, and presents an opportunity for the student to develop good class ethics, by having to find the time to complete the assignments he/she missed.
