Uh, well, that's the first time I have heard that particular rumor.
While the 2 year figure is rough (varies per rate and timing of classing up), you will definitely be in school full time.
The bulk (98%) of your day will be spent learning. The max amount of "work" you will be expected to do will be "field day" (housekeeping) work. You will be in class for about 8 hours per day, then expected to study a few hours in addition to that after school is out.
The rumor you heard from your dad's buddy is simply false. Grossly false.
