Slightly galling that people write this kind of drivel without examining any of the shaky premises it's logic relies on. Yes, in a perfect world, we can all learn our course material in advance and skate through our in-class education. More practical advice would be to build strong study habits and networking skills. Being able to get your work done with more time for editing/revisions and having access to other perspectives on the course work would have definitely improved the quality of my education. Building those habits and community take time and energy. I guess no simple hack there.
