In my AER222 -Engineering Design & Graphical Communication's course in my first year of university we had to do this test, expcept more in depth, more annoying and more time consuming (found here- to place us in groups for our term project so that we could "work togeather" better. It worked fine for my group but there were other groups that were so way off they almost failed the project because they just couldn't get along and work togeather.
