Replying to NS engineers!

 A question for those of you who have completed or are currently enrolled in engineering.  First off I am thinking about enrolling in an engineering program next fall. I know its going to be a big commitment and alot of work so please dont preach about that.  All I am wondering is how school has affected your shred time?  I know I am going to have to make sacarafices but some people have told me that realisticly I would barely have enough time to ski one day a week I dunno if i believe this.  So through your college years how many days a year would you average?
