@catzilla I'm also kidless and my incidental exposure to those of relatives (and the relative who's a teacher) hasn't covered modern schoolwork. I think at the university most everything is submitted electronically these days and professors/TAs would give you funny looks if you wanted to submit a printed copy, much less a hand-written one.
(This makes the central coursework submission system extremely critical and I'm forever thankful that I'm not one of the people looking after it.)
