More likely twice a week: at the start of the weekend when going home to parents (and their washing machine), and at the end of it when going back to uni.
Nope, 5 days a week, left home around 07.00, came home around 21.00. I even had a washing machine all of my own together with a house to put it in. I actually had a washing machine as a student as well, it was old but it worked - until a house mate destroyed it, that is.
